Abstract: A fuel tank having an upper compartment has a lower compartment separated from the upper compartment by means of a dividing member. The dividing member is sealably attached to the side walls of the fuel tank and has a small opening substantially centrally located therein. A first fuel tube extends through the top of the fuel tank into the upper compartment to a level near the bottom of the upper compartment. A second fuel tube also extends through the top of the fuel tank and through the opening in the dividing member to a level near the bottom of the lower compartment. A solenoid-activated valve is coupled to the first and second fuel tubes externally of the fuel tank. The selector valve is connected by means of a third tube to a fuel pump which pumps fuel from a selected one of upper and lower compartments to an engine. The selector valve is initially switched to select the upper compartments.
