Building a Brown Davis Tank

Since the beginning, Brown Davis has taken pride in the construction of our tanks, our Next-Gen Ranger 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

Does the tank come with all hardware required to fit?

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.

Will a Long range Fuel Tank affect my 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 is of course the point on the gauge you want to make is correct.

Will my "Distance to Empty"" still remain accurate?

Does my Long Range Fuel Tank required extra protection underneath?
