Fuel Tanks

In an age where the ability to travel further for longer is every four wheel drivers goal, having the fuel to get there and back is half the battle. TORQ4x4 caters for this by offering arguably the most engineered and tested range of long range and auxillary fuel tanks in the world. BROWN DAVIS!

The Brown Davis long range and auxiliary fuel tank range are an engineered solution for the ability to travel further when fuel stops are few and far between. Their tanks are designed to give maximum fuel capacity without affecting ground clearance and ramp over/departure angles, all whilst being exceptionally strong against the most rigorous of conditions. The Brown Davis long range and auxiliary tanks allow you to get to the most remote parts of Australia where a standard tank wouldn't take you.

The entire range of Brown Davis long range and auxiliary fuel tanks are constructed from high grade 2mm 14 gauge cold rolled steel coated with Aluminium to ensure maximum strength and durability. This gauge of steel is resistant to damage by impact, and therefore additional tank guards are not as necessary as standard tanks (most standard tanks are less than 2mm in material thickness). This material is specifically imported by Brown Davis based on critical specifications. Unlike aluminium, steel is not prone to fatigue from vibration and twisting as a tank is commonly subjected to in off road conditions. This fatigue resistance far outweighs any weight advantage aluminium may offer. However, the aluminium coating on the specific steel used by Brown Davis, offer's the strength of steel with the anti corrosion properties of aluminium giving you the best of both worlds.

The Brown Davis manufacturing facility uses state of the art equipment including computerised cutting equipment, folders and welders. Brown Davis also takes full advantage of the latest in 3D CAD modeling software to model tanks and components to suit each type of vehicle.

Some of the key design elements include:

Internal tank baffles: to prevent fuel surges when travelling on unstable terrain. When traversing through uneven and rugged terrain, or cornering quickly, the fuel inside a tank will slosh from side to side. This can cause fuel delivery problems in a tank that is running a little low and the fuel is able to travel away from the pick up area. Brown Davis tackles this issue by welding strategically placed baffles inside the tank which act as barriers to prevent fuel movement inside the tank.

Fuel Swirl Pot: Working in harmony with the internal baffle system, a fuel swirl pot surrounds the fuel pick up inside the tank. This ensures that fuel is always available even during excessive vehicle body movement which would otherwise cause fuel to slosh away from the pickup, potentially causing air to enter the system and potentially lead to the engine losing power. Double skinned faces behind mounting bracket surfaces: For maximum strength in those vital mounting points. When fully laden with fuel (allowing that 1ltr of fuel is approximately 0.75kg in weight), a full long range tank can weigh around 150kgs. All of this weight not only rests on the mounting points, but in uneven terrain, the weight applied to the mounting system can be multiplied. It is for this reason that Brown Davis manufactures their tanks with a second skin around the areas of mounting brackets. This ensures that even under the harshest driving conditions, fatigue will not cause a tank to fail at the mounts leaving you stranded in the outback.

Right-Angle Corner Support: Structurally speaking, a lot of strain is placed on any 90 degree right angle joins and folds, and are commonly a point of failure under heavy impact or structural twist. For this reason Brown Davis developed a way to strengthen both the join and surrounding material to ensure rigid strength at all 90 degree folded join intersections.

Magnetic drain plugs: To attract any metallic debris in the fuel tank. Sometimes fuel contains particles and contaminants, including foreign metallic particles. These particles can enter the tank in various ways. As such, a magnetic drain plug using extremely strong rare earth magnet is used by Brown Davis to catch these particles, allowing for easy tank maintenance and preventing the particles from travelling through the fuel system.

Horizontally fitted drain plugs: To prevent tank damage in the event of the tank coming into contact with terrain beneath the vehicle.

Submerged Pressure Test: Every tank, once it is finished construction, is thoroughly tested for leaks prior to final painting and packaging. One of the critical methods used to test the seal of each tank, involves pressurising the tank to a specifically calculated volume of air, then fully submerging the tank in water. Bubbles coming from the tank will indicate any leaks. Once the tank passes this test, it is deemed as being perfectly sealed and ready to be installed into it's buyers four wheel drive!
