Fuel Feed System
FUEL TRANSFER SYSTEM
This system is designed to pump the fuel from the Brown Davis auxiliary fuel tank into the vehicles standard fuel tank. At the flick of a switch fuel will be pumped into your vehicles standard tank to then be feed to the engine. An LED gauge is supplied to show driver the fuel level of the auxiliary fuel tank at all times. When the auxiliary tank becomes empty an automatic alarm will sound to tell driver to switch pump system off. This prevents pump from continuously running which can course pump failure. All parts and hardware for install are supplied
Fuel pumps burning out is now a thing of the past. Brown Davis has developed a new auxiliary fuel tank gauge, switch and buzzer unit to be supplied with most Brown Davis auxiliary transfer fuel tanks. the small unit is no bigger then a 10 cent coin and can be mounted nicely in vehicles dashes.
TANK FULL
FUEL NOT TRANSFERRING
The LED Gauge will show the auxiliary tank’s fuel level at all times, even when the pump is not running.
TANK FULL
FUEL TRANSFERRING
When the button is pressed, the fuel pump will commence transferring fuel from the auxiliary fuel tank to your vehicles main fuel tank. The round yellow LED light indicates that the pump is running.
TANK HALF FULL
FUEL TRANSFERRING
As fuel is being transferred from the auxiliary to the main fuel tank, the LED light will indicate the fuel level remaining within the Brown Davis auxiliary fuel tank. At any stage, the fuel pump activator button on the gauge can be pressed to stop the transfer of fuel.
TANK EMPTY
FUEL TRANSFERRING
When the auxiliary fuel tank is empty, a buzzer will sound prompting the driver to turn the fuel pump off. This is designed to prevent the fuel pump from any damage and increase its longevity.

Brown Davis manufactures a wide range of both Steel and Poly tanks so finding the right type of tank for your vehicle is crucial. Many factors need to taken into account so below are the highlights of both our steel and poly long range fuel tanks.
STEEL LONG RANGE FUEL TANKS
For 4WDs and tourers planning to head off the beaten track, our aluminized steel Long Range Fuel Tank is the best option.
POLY LONG RANGE FUEL TANKS
For fleet managers and customers sitting primarily on surfaced road, poly long range fuel tanks is a great option.

Building a Brown Davis Tank
Since the beginning, Brown Davis has taken pride in the construction of our tanks, our INEOS Grenadier (2023-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
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 of course is the point on the gauge you want absolutely correct.
Will my "Distance to Empty"" still remain accurate?
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.
Does my Long Range Fuel Tank require extra protection underneath?
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.
Will my vehicle’s clearance be affected by my Long Range Tank?
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.
