Can this tank fit with side toolboxes mounted on my tray

Generally yes, the filler neck has been designed to fit with most side toolboxes and lends itself to be modified on the day of fitting to suit the job.
Note: Occasionally if the tray and toolboxes are low profile and a tight fit with no space around then fitting the filler neck may not be possible, check out the pictures in the gallery for compatibility with your setup.
Note: additional fitting time may need to be charges depending on the extra labour required to make tank fit with the tray.

Can I fit this to an OEM twin tank model

Yes, this Auxiliary tank can be fitted to the OEM twin tank models for a total of 270lt in three tanks.

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.

Does this tank fit with style side ute back

No, the tank is designed to fit up between the rails on a typical tray design and would foul on the floor of the style side Ute body


How do I know how much fuel is left in the Auxiliary

With this transfer system fuel from the Auxiliary is automatically and continually topping up the main tank until there is non left in the Auxiliary. After driving enough kilometers to use 90lt from the Auxiliary the main gauge will start to go down indicating transfer is complete and there is no fuel left in the Auxiliary.

How does the Syphon system work

As fuel is removed from the original tank by the engine, it is usually replaced by an equal volume of air to prevent a low pressure occurring and the tank caving in (as would happen if you were to suck the air out of a plastic bottle).  This happens by air entering the tank via the original breather system.

If the original tank breather system is connected to the auxiliary tank pickup outlet, the fuel from the auxiliary tank will be syphoned into the main tank to take the place of the fuel removed by engine. There is no user input required as this happens automatically.  This will only occur if the auxiliary tank is vented to the atmosphere (even if through the original breather or pollution control system) – atmospheric pressure does the work.

Fuel will NOT be transferred from the auxiliary tank if air can enter the main tank in any other way – for example, if the main tank cap does not seal properly or leaks through a faulty vacuum valve where fitted, or a hose connection is leaking.

In operation, the main tank will remain full (or, more correctly, be continually topped up) until the auxiliary tank is empty.  The main tank will then start to empty, as indicated by the fuel gauge.

To ensure trouble free operation, the auxiliary tank should be treated as additional capacity, and NOT an ALTERNATIVE to the main tank.  I.e. don’t fill the auxiliary tank while leaving the main tank empty, as you will not get as much indication of your remaining fuel when the auxiliary tank empties and the main tank level starts to fall.

Fuel stopped transferring

If the syphon system has been working fine and then has stopped transferring fuel or only a partial amount is transferred there is most likely a vacuum leak in the main tank, this could be a spot weld leaking or a loose hose connection, main tank cap gasket, but the most likely cause is an old main tank cap itself.  The problem when they get a bit old is the pressure and vacuum release inside the cap is open all the time which stops a vacuum from being created in the main tank. A new cap usually fixes the issue or the old one can be glued up to seal it.  This is an easy process and simply involves filling up the middle of the cap with 5min epoxy.  As the Auxiliary tank has a vented cap this does not cause any issues.


Why is it so hard to fill my fuel tank after the tray was fitted

The filler of our LongRanger tank is in the same location as the OEM tank, the original steel filler neck on the vehicle does not lend itself very well to being lowered. Whether the standard fuel tank or a LongRanger is installed.
Unfortunately some tray manufacturers modify the fill neck to mount under the tie rail which is generally to low for the fuel to flow from the bowser to the tank or they rotate the fill neck and have a low point in the fast fill breather causing an air lock.
A well designed tray will have the fill neck mounted high and the fast fill breather with a gradual rise from the tank, below is a graphic for explanation.
During the fitting of a new tank it is important for the fast fill breather to have a gradual rise from the tank to the filler. If this is not done an air lock can form where fuel will accumulate stopping the air from escaping as you fill the tank, see picture below for do’s and dont’s of a filler neck install.

I have a special tray built for my cab chassis, will the tank be compatible

The LongRanger is designed to fit with all OEM and most aftermarket trays, If you have a custom or unique tray it would be worth browsing through the gallery to see how the LongRanger tank fits.  It should also be noted that fitting an aftermarket tray often results in a lower filler neck, this should be avoided to ensure the tank does not fill to slow.


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.


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.



Cross Break Strengthening. This is a simple and effective feature to aid in the stiffening of large flat panels. This technique reduces the risk of a fuel or water tank suffering from fatigue related stress cracks when travelling on extreme corrugations.


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.


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.


3 Year Warranty


Tanks will be free from any manufacturing defects in materials or workmanship for a period of Three Years from the date of purchase.
