Brown Davis 50L Auxiliary Long Range Fuel Tank – Jeep Wrangler JK (2007-2019) 2 Door

Brown Davis long range fuel tanks are an engineered solution to enable you to travel further with less fuel stops. They are designed to give maximum fuel capacity without affecting ground clearance, ramp over or departure angle, whilst being exceptionally strong to withstand the most rigorous of conditions. Brown Davis long range tanks allow you to travel to the most remote parts of the globe where the standard tank wouldn’t take you.

Brown Davis Aluminised Steel long range fuel tanks are constructed from 2mm aluminium coated cold rolled steel, to ensure maximum strength and durability. This gauge of steel is sufficiently resistant to impact damage that additional tank guards are not necessary. The aluminium coating on the specific steel used by Brown Davis, offers the best of both worlds with the strength of steel and the anti corrosion properties of aluminium.

This system is designed to pump the fuel from the Brown Davis auxiliary fuel tank into the vehicles standard fuel tank. At the flick of a switch, fuel will replenish your vehicles standard tank, which in turn is then fed to the engine. An LED gauge is supplied to show the driver the fuel level of the auxiliary fuel tank at all times. When the auxiliary tank becomes empty an automatic alarm will sound to alert the driver to switch the pump system off. This prevents the pump from continuously running, preventing fuel pump failure. All parts and hardware for installation are supplied.
