Fuel and range: standard vs Brown Davis
+60 L

+100%
more capacity
+500 km
extra range (approx.)
Standard figure is the factory capacity (60 L factory tank). Range assumes 12 L/100 km, typical for a loaded touring 4×4. Towing, sand and corrugations use more fuel. Never run a tank completely dry.

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.
