Factory fuelWith Brown Daviskm
Standard figure is the factory capacity (90 L factory tank). Range assumes 12 L/100 km, typical for a loaded touring 4x4. Towing, sand and corrugations use more fuel. Never run a tank completely dry.
+68 L is about 3.4 jerry cans you no longer carry on the roof.
How the transfer gauge works
Press to pump. It tells you when to stop.
Most Brown Davis transfer auxiliary tanks come with our gauge, switch and buzzer unit. It shows the auxiliary level at all times, and buzzes when the tank is empty so the pump is never left running dry.
The jerry can maths
3.4 jerry cans.
Or one Brown Davis tank.
The IG23A1 for the Grenadier replaces the factory 90 L tank with a 158 L Brown Davis tank in the same place. That extra 68 L is 3.4 20 L jerry cans you no longer strap to the roof.

Questions
Does the kit include everything I need?
Yes. Every Brown Davis tank comes with the brackets, hoses, fittings and step-by-step instructions. Auxiliary tanks also include the pump or changeover wiring and a gauge.
Will my fuel gauge still work?
Replacement tanks use the factory sender, so your gauge keeps working. Auxiliary tanks come with their own gauge.
Why is the distance-to-empty reading wrong?
The vehicle's computer still thinks it has the factory tank size, so the distance-to-empty figure will read low. Use the fuel gauge and your trip meter instead.
Does it change my ground clearance?
No. Our tanks follow the factory lines and keep your ramp-over and departure angles.
