If equipped, the fuel tank selector valve and fuel tank selector switch allows the use of 2 fuel tanks. When the fuel tank selector switch is in the front
position, the fuel tank selector valve will allow fuel to flow from the auxiliary fuel tank. When the fuel tank selector switch is in the rear position, the fuel
tank selector valve will allow fuel to flow from the aft-of-axle tank. The fuel gauge will read the correct amount of fuel in each tank depending on which
tank is selected with the fuel tank selector switch.
