Ford Ranger Super Duty

230 LITRE REPLACEMENT LONG RANGE FUEL TANK

The new Brown Davis replacement long-range fuel tank for the Ford Ranger Super Duty turns an already tough workhorse into a genuine long-distance weapon. In just 3 hours, your local Brown Davis dealer can remove the factory tank and fit a massive upgrade that adds an incredible 100 extra litres of fuel capacity.

That means one thing: no more unsafe jerry cans rattling around in the tray, no more stopping every couple of hours to refuel, and no more compromising on range when you’re working or touring remote country.

Built tough—just like the Ranger Super Duty

The latest Ranger Super Duty is designed for people who demand strength, reliability, and serious capability. The Brown Davis tank is built with the same mindset. Its heavy-duty construction is engineered to take hits, shrug off harsh terrain, and handle the real-world punishment that comes with owning a Super Duty.

Even better, the replacement tank actually improves ground clearance, giving you more confidence when tackling ruts, rocks, and off-road obstacles. Unlike many aftermarket additions, this tank doesn’t hang low or become a snag point—it enhances the Ranger’s capability.

Perfect for heavy towing

With the Ranger Super Duty’s massive towing and load-carrying capability, there’s no hiding the fact: towing big weights uses a lot more fuel. Whether you’re pulling a caravan, float, or work trailer, the extra 100 litres from the Brown Davis tank keeps your range steady and your stress low. No more hunting for fuel stops with a heavy load on the hitch—just confident, uninterrupted driving.

Smart features for real-world use

Brown Davis didn’t just make a big tank—they made a smart one.

  • Drain plug: Got bad fuel? Drain it out easily. Need to help out a mate stuck on the track? You can give them a top-up safely and cleanly.

  • Internal baffles: With so much fuel on board, slosh can be a serious issue. Brown Davis integrates strong baffles that prevent the fuel from surging around, keeping the vehicle stable and predictable even on rough tracks.

  • Swirl pot around the pickup: As the fuel level drops, the swirl pot ensures that the last usable fuel stays around the sender unit pickup point. In a tank this large, that’s absolutely essential to avoid fuel starvation on steep angles, corrugations, or when running low.

With more range, more durability, and more smart engineering, the Brown Davis long-range replacement tank transforms the new Ford Ranger Super Duty into the ultimate long-distance, hard-working machine—ready for towing, touring, and tackling Australia’s toughest terrain without breaking a sweat.

Building a Brown Davis Tank

Since the beginning, Brown Davis has taken pride in the construction of our tanks, our Toyota Hilux (2015 – PRESENT) tank is no exception. Our tanks are made with quality and care, from the materials we use to the stringent pressure testing, they are prepared for the harshest conditions.

Laser Cut Aluminized Steel

Manufacturing our steel tanks starts with laser cut aluminized steel. With this material, your tank will have the strength and durability of steel, and the anti-corrosive properties of aluminum to make sure their is no rust.

Folded Before Welded

Before welding the tank, we use specialized machinery to fold the laser cut aluminized steel to decrease the amount of time and labor put into welding. Folded parts also have superior strength to welded parts.

High Quality Welding Every Time

Next, our experienced welders add the brackets, swirl pot and baffles to the tank and then weld it all off.  We use jigs to locate the brackets for each individual tank so installation is as consistent and easy as possible for every vehicle.

Pressure Testing

Lastly, we take it through an air pressure test. This involves a soap test, submersion test and a pressure gauge. These techniques help us identify any rare leaks and where they’re coming from. If air isn’t coming out, fuel definitely isn’t.

Frequently Asked Questions

Yes. All Brown Davis Fuel Tanks come with everything required to be fitted to your vehicle. This includes auxiliary (secondary) Fuel Tanks which come with electric fuel pump, hoses, wiring and fuel gauge.

After the installation of any Long Range Fuel Tank the vehicles fuel gauge (needle fuel gauge) will change slightly. This will be different in each vehicle depending on the tank shape. Some tanks will remain on full for a few hundred kilometres due to the extra height in the new tank. In most of the more popular tanks, we supply a special float arm to go with our tank, this gives a more accurate reading for the gauge. What we do make sure of is that the vehicles low fuel light and empty point is accurate on all tanks. This of course is the point on the gauge you want absolutely correct.

In short, the distance to empty function on your trip computer won’t remain accurate with your new Long-Range Tank. This is because the vehicles ECU (Engine Control Unit) has the volume of the original tank size programmed within it. However, with many of our Long-Range Replacement Fuel Tanks being approximately double the volume of the original fuel tank, you can simply double the ‘distance to empty’ reading to roughly estimate your new driving range.

For certain makes and models there are unaffiliated 3rd party software programs that can re-write information to your ECU, for example, there are options for the Ford Ranger. We believe this fix is ultimately unnecessary, however, if you wish to have your ‘distance to empty’ read true for the new fuel volume, we recommend researching if there are options available for your vehicle. 

Good news is, your fuel gauge will remain accurate, as the float inside the tank will indicate how much fuel is inside the tank, so your readings going from Full, to ¾ to ½ right down to empty will remain accurate. Furthermore, your low fuel warning light will work as intended.

We recommend to zero your odometer when you refuel and check your fuel consumption. Over time you’ll be able to establish how far you can travel in different driving conditions, i.e. towing, sand, dirt, etc. 

If you are planning to go off-road, we recommend our Steel Long Range Fuel Tanks where extra protection is not necessary. Made from 2mm Aluminised Steel, strength and durability are without question. Need more convincing? Check out the boys from All4Adventure and ExploreLife, both who run our steel tanks and have seen their fair share of remote and rugged environments.

Our Long Range Replacement Fuel Tanks are designed to make no impact to your vehicle’s stock clearance and ramp over angle. We design our Fuel Tanks with not only touring but hard four-wheel-driving in mind, therefore, maintaining stock clearance is paramount.
