HMMWV In Scale

HMMWV Auxiliary Fuel Tank

Some HMMWV's that are expected to need extended range (such as SOCOM GMV's) without being able to refuel have had auxiliary fuel tanks installed.

The quickest and easiest way to identify HMMWV's with the auxiliary fuel tank installed is to visually check for the presence of a second filler tube. The auxiliary tank filler tube is to the rear of the main filler tube on the right-hand of the vehicle.

Another method to identify trucks with an auxiliary fuel tank installed is to check for the presence of an auxiliary fuel tank selector switch. The auxiliary fuel tank selector switch is located on the instrument panel of a HMMWV with an auxiliary fuel tank.
