ABSTRACT:
A fuel delivery system10includes a reservoir12in a fuel tank14; a fuel pump16in the reservoir for sending fuel at an engine; a jet pump18including a venturi tube22adjacent to a nozzle24to draw fuel from the tank into the reservoir; a cup25coupled with an end of the venturi tube for containing an amount of fuel; and a jet valve20permitting fuel drawn by the jet pump to enter the reservoir from the fuel tank and, preventing fuel that enters the reservoir from returning to the fuel tank. The cup traps fuel inside the jet pump so that fuel accumulates in the venturi tube and in the cup to a level above the nozzle thereby permitting the jet pump to draw fuel from the tank into the reservoir.
