ABSTRACT:
A modular fuel delivery system including a reservoir in fuel tank, an electric high pressure pump in the reservoir fed only from inside the reservoir, and a jet pump fed only from the fuel tank and discharging into the reservoir to keep the latter filled and energized from the high pressure pump. A check valve is disposed between the jet pump inlet and the fuel tank to prevent backflow into the fuel tank. A partition on the bottom of the reservoir separates the jet pump discharge from the high pressure pump inlet and defines a standpipe around and above the jet pump discharge so that the jet pump stays submerged in fuel when the high pressure pump empties the reservoir. The pumping efficiency of the jet pump when submerged is better than when dry so that the delay in restarting the engine after the both the fuel tank and the resvoir are pumped empty is minimized.
