How will the trip computer work?

Unfortunately the 200 series trip computer is unable to be modified to work with the new larger tank capacities. The “Driving Range” function will only display the driving kilometers before empty based on the factory tank capacity.

How come when I transfer fuel to the main tank the “Driving Range” is not updated?

As per the owners manual on page 158 (2008 model) if only transferring a small amount, “when only a small amount of fuel is added the display may not be updated”.
The other reason it will not update is because the on board computer looks at the fuel level when you turn the vehicle off.  It then looks at the level when the vehicle is turned back on, if there is a significant difference and the tank is now reading full it automatically resets the driving range based on the factory tank capacity and the historical fuel economy.  When transferring fuel while driving there is no difference between the gauge when the car is turned back on after being off.
If this is a major issue for you the only work around is to connect the transfer pump direct to the battery (rather than our recommended ignition power source) and transfer the fuel while the vehicle is turned off and parked.

Do the LongRanger Tanks compromise ground clearance?

This varies between models, but in most cases the ground clearance is actually improved. With our 70L versions we mount the spare tyre in the same position as vehicles with a factory sub tank option. All other models have improved ground clearance due to the relocation of the spare tyre

Are the tanks that replace the sub and your auxiliary the same?

No, they are similar and share a common shape but have different fittings and the fitting kit is completely different between an Auxiliary and a replacement tank.

When I fill up with “Driving Range” at 0 I can only get 80L in the standard tank?

It is not uncommon for there to be between 8L and 15L in a tank with the gauge on empty. In fact the Toyota 200 series Landcruiser owner’s manual states that when the warning light comes on in single tank models there is about 15L or less. So as new engines become more sophisticated Toyota is designing a bigger safety margin in to avoid possible damage to engines with people continually running out of fuel.

Why can’t I use the tanks independently like the 100 series?

With either the Long Ranger Auxiliary tank or the factory sub tank option it is simply just not economical to modify the system to run on either tank independently and tampering with the sophisticated electronics may lead to all sorts of problems.

Does the tank have anti-surge dam and baffles

Yes, to maximise fuel usage from the new larger tank we have baffles and a built in chamber around the fuel pickup unit to help avoid pickup cavitation sucking in air, these features can be especially useful when accidentally running low on fuel or driving on sloping terrain.
With larger tanks having bigger surface areas baffles also help add strength for those odd knocks and dents you can’t avoid.

Does The Long Ranger have a drain plug

Yes, although some OEM and aftermarket tanks don’t come fitted with a drain plug we believe this is a must have feature when traveling the outback as you never know if you have to drain the tank in the advent of picking up a bad load of fuel.

Will the factory sub tank fit my vehicle that has only one standard tank

Sort of, You will need to purchase a tank and the mounting straps. Then you need to figure out how you will fill it, how will you get the fuel out of it and how will you mount it, as the captive nuts to bolt it to the floor are not there on these models. If you want it to work automatically like the factory setup you will also need to purchase the transfer pump which is located in the main tank, numerous electronics and plumbing.There have been estimates of approximately $3000 (as at 2-2-08) for the genuine parts alone from Toyota

Is there a way I can maximise the fuel usage from the LongRanger Auxiliary tank

This is just a little tip to help those of us that like to use every last drop. The pickup is located at the front right corner of the tank, so although we have built a dam and baffles to help pickup all the fuel on those occasions you need every last drop we recommend having the front right corner of the vehicle be slightly lower to pump every last drop out of the tank.
The pumps can be run for a short time without fuel in the tank, so on the odd times you need to use all the fuel this is not an issue.

Why is there separate listings for diesel and petrol models

Although most aftermarket manufacturers only build one tank to suit both models for a longrange tank to be legal in Australia and most other countries around the world all road registered petrol engine vehicles need to be fitted with an additional carbon canister to ensure their anti pollution systems continue to comply with the regulations for vehicle registration, from 2015 The LongRanger is the only legal tank in Australia with our kits  supplied standard with a carbon canister.


Do I have to transfer fuel when my main tank gauge is on 1/4 like the operating manual says?

No, you can transfer fuel from the Auxiliary to the main whenever you choose, but the automatic pump cut off timer has been setup in our factory for this optimal fuel level in the main tank, below are some words on the design of this system for a better understanding.
We have chosen this level of fuel in the main tank mostly for safety, if you start the transfer process at this level and there is a malfunction for some reason and the fuel does not transfer to the main tank you will notice the gauge in the main tank continue to go down as you drive rather than going up like it usually will.
By having a 1/4 of a tank left rather than nearly empty you will have time to make a judgment on what needs to be done to sort it out, although very unlikely, things like a blown fuse or blocked fuel filter on the transfer pump could cause the fuel not to transfer.
If you wish to transfer fuel before the main tank gets to 1/4 the automatic pump cut off timer will not have been operating for long enough to activate, in this case when the main tank is full the pump can be turned of manually.

A detailed operating manual is provided in the fitting kit.

How do I know when to turn the transfer pump off

Our transfer pump system has a timer based automatic pump cut off so you don’t need to worry about buzzers or running your pump dry if you forget to turn it off.

If the auxiliary is bigger than the Main tank we have a timer to turn the pump off so you don’t overfill the main tank, we have a second timer that will turn the pump off when the Auxiliary is nearing empty.
With a transfer rate of Approximately 1.7L per minute the pump can be turned off or on at any stage to transfer small amounts of fuel or you can simple push the button to activate the transfer process and leave it for the timer to automatically turn the pump off.
Our kits are supplied from the factory with a comprehensive user manual on how to use the system and the timer module has been setup with specific settings to suit each vehicle application for quick and easy installation.

How will I know how much fuel is left in the auxiliary tank

A compact LED Gauge is mounted in the dash to show approximately how much fuel is left.
Once the automatic timer has cut in there is a flashing light to indicate the pump will soon turn off.
See the features tab for an in depth look at the gauge.

How do I transfer fuel to the main tank

Depending on how you want to use your new Auxiliary fuel tank, you can either activate the pump to transfer a small amount of fuel as you drive to keep the main tank topped up and transfer the weight from the auxiliary tank to the main tank and turn the pump off when the main is full.  Or you can just wait till the main tank gauge is around ¼ and transfer the fuel at the touch of a button and let the timer turn the pump off automatically.  NOTE: If the Auxiliary tank is larger than the main tank you will be able to transfer a second amount of fuel in order to completely empty the auxiliary tank. An owners manual update and user manual are provided in the fitting kit with a guide to the operating procedure of the Longranger.

Can I Transfer fuel at any stage

Yes you can.  We generally recommend starting the transfer when the main tank gauge is about ¼ full,  but if you are loaded up on a big trip it is good practice to distribute the weight by perhaps pumping small amounts of fuel from the Auxiliary tank to the Main tank.  A detailed user manual is provided in the kit to give you all the info to take advantage of this great accessory.

Read More About Our Transfer Pump

Transfer Pump

Compatible with All Fuels including new blended Diesels, Solid Sate Cube pumps have low power requirements (about 1-2 amps at 12 volts) and operate without troublesome seals or diaphragms. Built-in pressure relief and are Self Priming to 300mm (we test our pumps to 500mm with no issues). They have a free flow rate of 2L per minute and 1.71L per minute when used as a transfer pump on a typical auxiliary tank application with 8mm fuel lines, and fuel filter installed.

One of the most important factors in the reliability of these pumps is the internal electronics and the sealing used during manufacture. We have tested several other cube pumps sourced from china and the US and found the best there is.

In one test we do, many of the cheaper pumps that are sold in the Australian market do not pass a water immersion test and stop immediately due to poor sealing. Others will only run for 10 or 15min after being submersed in the water. The pumps we use have to handle being submersed completely under water while pumping 120L of fuel, they are then tested for another 1000 hrs to ensure they keep running. This is extremely important when used on a 4wd as frequent river crossings can be an every day occurrence.

Note: Cube fuel pumps are not compatible with EFI fuel systems.

These pumps are also suitable for applications requiring an external electric fuel pump, including replacement of old mechanical pumps on low and high-pressure carburettor-equipped cars, vans, Motor Homes, farm equipment and light trucks or use as a Diesel lift pump, they can also be used to replace unreliable fuel pumps on Classics with 4cyl or 6cyl power output of up to 150bhp

Key features:

  • Fuel Compatibility: Compatible with petrol (gasoline), diesel, biodiesel, blended alcohol fuels and fuel additives.
  • Solid State Reliability: Proven on thousands of applications. No electrical contacts. No bearings or diaphragms to wear out or fatigue. Lasts four to five times longer than many other electric fuel pumps.
  • Easy to Install: Small size and two-bolt installation makes for easy fitment. For best results, mount the pump close to the fuel tank and below the liquid level.
  • Eliminates Vapour Lock: When properly installed on most vehicles a constant, smooth, dependable supply of fuel under pressure is assured in the hottest weather.

General Features:

  • 300mm minimum dry lift
  • 2L per minute free flow rate
  • 4-7 PSI
  • Transient Protection
  • State of the art Electronics
  • Sealed Electronics
  • Reverse Polarity protection
  • Built in check valve
  • 1.6 amp average
  • Self Priming and Self Regulating
  • Inlet And Outlet Thread Size: 1/8-27 NPTF (1/8 gas
  • Operating Temperature Range: -30C to 80C


Lightly oil the threads on the hose fittings. Apply torque in a continuous manner to 15 ft-lbs. The pump and fitting threads are dry seal threads which do not require thread sealant if the fittings are properly installed.

Apply a  74 micron fuel filter on the inlet side of the pump to protect the pump from contaminates in the fuel. This will ensure trouble free operation of the fuel pumps for many years.

Select a mounting location as close to the fuel tank as practical and not more than 300m above the bottom of the tank. Generally speaking, fuel pumps push fuel better than they draw fuel. The pump should generally be mounted with the outlet elevated above the inlet to assist with priming ability and also helps purge the system of air. Additionally select a location away from excessive heat sources.

Apply pump to a properly fused circuit of 3-5 amps.

Trouble Shooting:

If the pumps fails to make a clicking noise with power applied make sure there is proper power to the pump and the voltage is correct. Also check fuse, wire connections and proper grounding of the negative lead wire.

If the pump makes clicking noise but fails to deliver fuel make sure there is fuel in the tank and the filter is not clogged.


Do I have another hole in my bodywork for this twin filler setup?

No, the twin filler supplied as part of our kit has a single cap and utilises the existing hole for the OEM filler, our unique design has two holes for the fuel nozzle, you can choose the main tank or the auxiliary.

Worried about poor fuel quality at the only place in town you can get fuel or filling from drums in remote locations?

A good idea if you are concerned about contamination in your main fuel tank that supplies the engine is to utilise the standard filter we install with our auxiliary tanks.

With this twin filler setup you can just add fuel to the auxiliary and then transfer the fuel across to the main tank, any contamination will either be in the auxiliary or the filter which can be replaced at your next service.
It’s a little bit slow as the pump is rated at 1.7 lt/m, but still a good option to ensure trouble free operation when in the middle of nowhere!


I have a plastic taste in the water

Our tanks are made from stainless steel and we use food grade pvc hose so there should not be any issues.
If you regularly fill from a garden hose it is a good idea to let it run for a while before filling the tank as the water lying in the hose can be tainted and transferred to the water tank every time you fill up!

How do I fill the water tank

Most of our water tanks come with an under bonnet filler so we do not drill any holes in your new car.
Although we don’t recommend doing it at full town water pressure a good tip that can also be set up, with the correct fittings on our tap you can use your standard hose to back fill the water tank, you know its full when it comes gushing out the breather 😉

Water leaks after filling up

Most of our water tanks have an under bonnet fill, and a breather to allow the water to come out when you turn the tap on.  We do try to have the breather up as high as possible during the installation but sometimes when you fill up the water level can be higher than the top of the tank and breather, so it is not unusual to have a small amount of water come out the breather in these situation or when the tank if full and you go up or down a very steep hill.
As the breather is in the very top of the tank the amount that can come out would only usually be what is in the filler hose.

Can I fit a water pump

Yes, although our combo tanks are designed to have the water sit up high under the floor pan and come with a gravity fed tap in the kit, the tank is made with a second outlet, should you wish to add a shower unit or a water pump in the future simply take the bung out and screw in the appropriate 1/4 bsp fitting.

Can water leak and contaminate the fuel

No, despite the tank looking to be one single unit, the fuel tank is made from aluminised steel and is separate from the stainless steel water tank, these are designed to be interlocking and glued together with polyurethane glue between the two different tank surfaces.


Do I need an extra protection plate

Standard OEM fuel tanks manufactured with plastic construction or thin turn plate often require an extra bash plate for protection. Being made from 2mm “aluminised steel” with internal baffling our tanks are designed to handle the odd scrap and dint you would expect with general 4wd use or outback touring and offer excellent strength and durability in these situations. Depending on your intended vehicle use if you often find when out on the trail turning back is not an option and your forced to test your vehicle to it’s limits or if you’ll be doing lots of hard off roading in steep and rocky terrain we may have other options more suitable for you such as a smaller tank with more ground clearance or a “HD” version with a heavy duty protection plate welded directly to the bottom of the tank.


Does this long ranger fuel tank fit with towbars

Generally we try to make our tanks fit with most towbars on the market at the time we design our tank, occasionally a particular towbar is built in such a way that to make our tank compatible would result in very little extra fuel capacity gained,  if there are any known issues with specific models we mention this on the specifications tab under “other mods”


Where are the tanks made

While there is a popular belief that all the big brands are made in a country with a cheap manufacturing base in the same factory with a different badge at The Long Ranger we still design and manufacture our tanks in Australia were it all started way back in the late 70’s.  We are a family run company based in Newcastle employing local people and that’s not about to change anytime soon.

Is the GVM (Gross Vehicle Mass) affected

No, adding a tank is the same as any other accessory and is utilising the vehicles payload capacity IE: anything added to the vehicle from the manufactures specification is using the payload capacity, whether it be driving lights, a set of rubber mats, a LongRanger fuel tank or the kids. As with most vehicles from a manufacturer the standard springs are not designed to cope with a constant full load on an extended trip, we recommend fitting a set of heavier rated springs such as those from Old Man Emu that have been designed to carry the extra weight of a fully loaded vehicle set up for camping.

Do the tanks come complete ready to fit

Yes they do, you may have heard on the grape vine that some aftermarket tank suppliers ship their products with poor fitting instructions and incomplete kits that make a trip to the local auto store a necessity to finish the job. At the LongRanger we supply comprehensive installation instructions with lots of photos to ensure the job is done as efficiently as possible and a complete installation kit ready to install so your local fitter can be rest assured there will be no expensive delays sourcing bits and pieces to finish the job!

Is the LongRanger design compatible with other accessories

There is nothing worse than buying an accessory to find it’s not compatible with something else you have fitted, we might not be first to market, but that’s because we try our best to design our long range tanks to be suitable with all models in the range and most other popular accessories you might want to install either now or in the future. Although we have designed our tanks with maximum compatibility in mind, if you have something specially fitted to your vehicle that is of concern we have provided a good selection of pictures in the gallery showing the installation to give a clear idea where The LongRanger fits under the vehicle.

Where can I purchase a LongRanger fuel tank

If you can’t make it to the Newcastle factory at 65 Northville Drive Barnsley NSW, all our products are distributed by ARB 4×4 accessories. For sales and support around Australia you can find a list of all the ARB stores Here

How long is the warranty period

All LongRanger manufactured products are covered by a 3-year warranty.
Note: There are some third party components not made by The LongRanger such as fuel pumps, sender units and switches etc found in some kits that come with their own 12 month manufacturers warranty.

What are the tanks made from

All LongRanger fuel tanks are made from Aluminised steel. This product is manufactured by the steel mill using 2mm (14gauge) cold rolled steel with a thin aluminium coating applied during the manufacturing process. Aluminised steel offers excellent weight vs. strength and durability when compared to lighter aluminium that just doesn’t have the raw strength to stand up to the hard knocks the underneath of a vehicle can suffer or the heavier Stainless steel that is more prone to fatigue cracks caused by embrittlement in the heat affected zone from the welding process.

Have you got a unique setup?

Below is a list of standard accessories we have checked for compatibility with our tanks and strive to ensure compatibility with.
Alternatively if you have something a little different please check our pictures and advise the sales staff to allow extra time for fitting if you think you have something that might cause a problem on the day or if you are planning an extensive list of modifications to your truck use our pictures to make sure our tank will fit in with your plans for the best chance to get it setup the way you want.
As our fuel and water tanks are designed to make use of space under your vehicle anything else fitted could cause and issue on the day of fitting, things such as trundle draws, air tanks, tipper trays, water tanks, custom trays with low floors, batteries, extra tyre, structural chassis changes etc can all cause an unexpected issue, delays or even non fitting in a worst case scenario.

While our tanks have been primarily designed to fit Australian models prior to early 2000, Since then car manufacturers have been getting smarter and making their cars on global platforms so they generally fit vehicles of the same model in other countries.
Your local ARB dealer may be able to assist with any fitment questions as they may have some prior experience with your particular model.
Another good resource is to check our photo gallery for an idea of the shape and location of our tank.  Some common areas to look for possible issues with models in other countries would be: is the filler on the same side, do the chassis look the same around the tank location, If choosing a replacement tank, is the genuine tank the same capacity as with the genuine Australian spec model, Does the exhaust run in the same place, Do you have different genuine or non-genuine accessories fitted that may not be available in Australia for us to verify that may be affected with a new fuel tank.



The vehicle entered production in September 2007 and was available for sale from September. It became available in Venezuela for sale early in November under the local nickname of “Roraima” (taken from Mount Roraima).




Switch/Gauge Timer. All you have to do is turn the transfer pump on when your main tank gets to ¼ full, our timer module will take care of the rest.

No worrying about when to turn it off, no annoying buzzers.

A neat round profile including a LED display with push button switch for transferring fuel. The switch/gauge has an automatic dimming function for easy on the eye night driving.  With its small footprint (20mm hole x 65mm depth) this unit will fit neatly into just about any modern vehicle.

Another unique feature incorporated in most of our Auxiliary tanks is the timer function to turn the transfer pump off automatically. We have incorporated two timers to turn the pump off, these are activated when the auxiliary tank is getting low or when the main tank is almost full.  The timer modules are set at our factory to suit each tank and shipped ready to use as the settings vary depending on the size of the Auxiliary and Main tanks.

A comprehensive owners operating manual is provided in our fitting kit outlining all the details to maximise the use of this great feature. Along with the LED bar style gauge we have a “pump on” light to remind you it is transferring fuel and when the pump has entered the countdown mode to turn off automatically it will start to flash to let you know it’s almost completed the transfer. Switch/Gauges are covered by the manufacturers 12 month warranty.

ledaLeading Edge Deflection Angle. Incorporating a leading edge deflection angle on the front lower section of the fuel tank allows road debris to be easily deflected.  This means the tank is marginally smaller in capacity, but in those tricky situations going over mounds of dirt and rocks you are less likely to get hung up than on a tank which hangs to low with a square leading edge.


max-foldMax Fold. Using this feature we maximise the sheet by making the base of the fuel tank from one side to the other in one continuous piece of metal.  This ensures the minimum amount of heat and possible stress from welded joins.


hptHydrostatic Pressure Test. At The LongRanger factory each & every fuel & water tank undergoes a pressure test while being placed under water at a maximum of 5 psi.

pac-manPac-Man. You guessed it, we have pacmen inside our tanks working away to help strengthen the high stress areas. While your happily driving along those rough corrugated outback dirt roads listening to your favourite country music in the air-conditioned comport of your new 4WD, these little guys are busy working away holding things together while the underside of your vehicle is coping a pounding.


senderSender Unit. To ensure the safe operation of your vehicle it is important to be reliably informed about the current fuel level at all times. Our 0-90 ohms senders measure the level in the tank and send the information to the LED display. The fuel sending unit has a float that connects itself to the metal rod. The end of this rod is connected to the variable resistor that resists the electrical flow. Our sender units are covered by the manufacturers 12 month warranty.

Sender Unit

shapeShape. Good design practices are what make a fuel tank both usable and functional. Some manufactures build cheap large sheet metal boxes and bolt them under a vehicle and call it a fuel tank. At the LongRanger we take the design a little more serious. Attention to detail and decades of experience building tanks has taught us what it takes to make a great product.


bafflesBaffles. help add strength to the bottom of a tank, this is especially important for a 4WD when bottoming the tank out on obstacles with the pickup unit sitting on the bottom which could be damaged, if the new tank design is lower than the OEM tank this is even more important with the tank being more vulnerable to accidental obstacle contact. A well designed longrange tank should incorporate baffles for improved offroad performance as baffles also help retain the fuel around the pickup unit.  With longrange tanks generally being longer or wider than the OEM tank when low on fuel it can “run away” from the pickup when driving in undulating terrain and possibly cause the engine to starve for fuel leaving you in an unpredictable situation and potentially unsafe location.
