Whether you’re taking on everyday road trips or embarking on extreme off-road adventures, the Brown Davis long-range fuel tank is engineered to meet the demands of the toughest journeys.
105 Litre Auxiliary Tank: The Perfect Solution for Touring
The first option in this line-up is the 105-litre auxiliary tank, which is seamlessly installed behind the vehicle’s rear axle. This auxiliary tank is the perfect upgrade for those who need extra fuel capacity without sacrificing practicality. With a massive increase in fuel storage, the 105-litre tank more than doubles the Grenadier Quartermaster’s fuel capacity, giving you the freedom to explore further without constantly worrying about fuel stops.
This tank is ideal for road trips, longer drives, and general daily use, offering peace of mind for those who prefer to travel off the beaten path.
168 Litre Two-Part Auxiliary Tank: For the Ultimate Adventure
For the true adventurer, Brown Davis offers the two-part 168-litre auxiliary tank, designed for the most extreme expeditions. This options consists of the 105 litre tank, but ads a smaller 65 litre tank behind it for a total of 168 litres. This larger setup offers serious off-road enthusiasts the ultimate range, ensuring you can tackle the most remote regions with confidence. Whether you’re crossing deserts, climbing mountains, or venturing through the bush, the combined 168-litres provides a huge capacity, pushing your Grenadier Quartermaster’s fuel range to an impressive level.
Seamless Integration & Installation
Both tanks are designed to be fully integrated into the vehicle, transferring fuel directly into the main tank, allowing for easy management of fuel levels. Brown Davis has ensured that each system comes with all the necessary hardware and parts required for a full installation, making the upgrade process as smooth as possible.
Vehicle Spare Wheel Removal: To accommodate the larger tanks, the vehicle’s spare wheel will need to be removed, creating the perfect space for installation.
Tanks for Tray Vehicles: For those with aftermarket tray setups, a standalone filler can be installed, allowing for added convenience and flexibility. (NOT SUPPLIED)
Compatibility with Standard Tubs: Tanks are supplied with a new dual neck filler, allowing you to utilise fast flow diesel pumps. Hoses to suit vehicles with standard tubs are supplied, ensuring compatibility across a wide range of setups.
A Total of 258 Litres: Unstoppable Range
The most incredible feature of the Brown Davis long-range tank system is the staggering total fuel capacity it offers. When combined with the factory main 90 litre fuel tank, your INEOS Grenadier Quartermaster can achieve a total fuel capacity of 258 litres—a truly massive range that sets you up for even the most extended adventures. Imagine the freedom to journey across vast expanses of wilderness, remote locations, and off-the-grid destinations, all without worrying about running out of fuel.

Fuel Feed System
Fuel Transfer System
The Brown Davis Fuel Transfer System automatically transfers fuel from the auxiliary tank to your vehicle's main fuel tank at the press of a button. An LED gauge continuously displays the auxiliary tank's fuel level, while an integrated buzzer alerts the driver when the auxiliary tank is empty, helping prevent the fuel pump from running dry and extending its service life.
The compact switch, LED gauge, and buzzer assembly is approximately the size of a 10-cent coin, allowing for a clean and convenient installation within your vehicle's dashboard. All required components and installation hardware are included.
System Operation
| Operating Condition | Description |
|---|---|
| Tank Full – Fuel Not Transferring | The LED gauge displays the auxiliary tank's fuel level while the transfer pump remains switched off. |
| Tank Full – Fuel Transferring | Press the transfer button to begin pumping fuel from the auxiliary tank to the main fuel tank. The yellow indicator light confirms the fuel pump is operating. |
| Tank Half Full – Fuel Transferring | The LED gauge shows the remaining fuel level as fuel is transferred. The transfer process can be stopped at any time using the gauge button. |
| Tank Empty – Fuel Transferring | An audible buzzer alerts the driver when the auxiliary tank is empty, indicating the fuel pump should be switched off. This protects the pump from damage caused by running dry. |

Brown Davis offers both Steel and Poly Long Range Fuel Tanks, allowing you to choose the best option based on your vehicle, driving conditions, and intended use. Compare the key features and benefits below.
| Steel Long Range Fuel Tanks | Poly Long Range Fuel Tanks |
|---|---|
Drain PlugAll Brown Davis Steel Long Range Fuel Tanks include an integrated drain plug, allowing contaminated fuel to be safely drained or fuel to be collected when required. Internal BafflesBuilt-in internal baffles reduce fuel slosh and movement during driving, improving vehicle stability while increasing the tank's strength and durability.

Best Suited For: Off-road enthusiasts, remote touring, overlanding, and demanding conditions where maximum durability is essential. |
Lightweight ConstructionBrown Davis Poly Long Range Fuel Tanks are typically 10–15 kg lighter than comparable steel tanks, making them an excellent choice when reducing vehicle weight is a priority.

Building a Brown Davis Tank
Every Brown Davis Long Range Fuel Tank is engineered and manufactured to the highest standards, ensuring exceptional strength, durability, and reliability. From premium materials to rigorous pressure testing, each tank is built to perform in Australia's toughest conditions.
Laser-Cut Aluminized SteelEach steel tank begins with precision laser-cut aluminized steel, combining the strength of steel with the corrosion resistance of aluminum. This premium material delivers outstanding durability while helping to prevent rust. |
Folded Before WeldingBefore welding, each panel is precision-folded using specialised machinery. Folding reduces the amount of welding required, improves manufacturing accuracy, and creates stronger joins than welding alone. |
High-Quality WeldingExperienced fabricators weld every bracket, swirl pot, and internal baffle with precision. Purpose-built jigs ensure consistent fitment and quality across every fuel tank produced. |
Pressure TestedEvery Brown Davis fuel tank undergoes comprehensive pressure testing, including air pressure, soap solution, and submersion testing, to detect even the smallest leaks before leaving the factory. |
Why Choose Brown Davis?
- Precision laser-cut aluminized steel construction.
- Folded panels for increased structural strength.
- Professionally welded by experienced fabricators.
- Internal baffles and swirl pot for improved fuel control.
