BD Tank Team on the road · 4WD 24/7 Kimberley series, 2026
Weeks in the Kimberley. Days from a bowser.
Shaun Whale and Graham Cahill took the 4WD 24/7 rigs deep into the north-east Kimberley: flooded tracks, the Drysdale River, King George Falls and an abandoned track to the Berkeley River that hadn’t been driven in 30 years. Out there, fuel range decides how far you can push. Both rigs ran Brown Davis long range tanks.

Fuel filter bracket kits · keep the fuel in your new tank clean
Don’t let one bad fill-up ruin your holiday.
A bigger tank means more fuel from every fill, and on a remote trip some of it comes from a bowser you know nothing about. One batch with dirt, water or algae in it can block your main filter and leave you in limp mode, a long way from a mechanic.
Fit a Brown Davis pre-filter with your new tank and the nasties are caught before they reach your factory filter, pump and injectors.
How it works · from your tank to your injectors
The pre-filter takes the hit. Your factory filter doesn’t.

Your vehicle’s fuel tank
Every fill-up goes in here, including from bowsers, drums and jerry cans you know nothing about.

02
Brown Davis pre-filter
20 micron element and a clear water bowl. It takes the hit from a bad fill-up, and you can see and drain what it catches.

03
Factory filter
About 2 micron. With the big stuff already gone, it only has fine particles left to deal with, so it lasts and keeps flowing.

04
Pump and injectors
Clean diesel only. No limp mode, no blocked filter on the side of the track, no costly repair.
Reaches your injectorsClean diesel
Why 20 micron?Common rail diesels run about 2 micron main filters to protect the pump and injectors. A 20 micron pre-filter is 10 times coarser, so it takes the worst of a bad batch before your main filter blocks and drops you into limp mode.
Water and algaeAlgae in diesel grows in the water. The clear bowl lets you see water building up and drain it on the side of the track, so the sensors downstream keep working.
In the boxVehicle specific 3 mm zinc plated bracket, 20 micron filter with water bowl, quality fuel hose, corrosion proof brass fittings, 8.8 tensile hardware and stainless clamps.
Whether it’s a cab chassis with a motorhome body or a van converted into a camper, a Brown Davis tank can effectively double your fuel capacity. Cover more ground between fills, and spend the trip enjoying the place instead of planning your next fuel stop. That matters most off the beaten path, where fuel stations are few and far between.

Must-haves in a tank this big
Internal bafflesIn a tank this size, fuel slosh is a real problem. Baffles stop the fuel surging on hills, corners and under brakes, and add strength to the tank.
Swirl potKeeps fuel around the pick-up point, so the pump keeps drawing fuel on steep roads and when the tank is running low.

100 litres of diesel is five full 20 litre jerry cans. That is five cans to strap down, five to lift, five to pour. Or one tank that sits against the front wall of your tub and gravity feeds your main tank at the flick of a switch.
