Claim Text:
1. A fuel supply system comprising: a fuel pump configured to pump fuel from a first fuel storage location to an engine; a jet pump configured to receive an auxiliary supply of fuel from the fuel pump and to return the auxiliary supply of fuel plus an additional flow of fuel drawn from a second fuel storage location to the first fuel storage location; a jet pump supply line having an inlet in fluid communication with an outlet of the fuel pump and having an outlet coupled to an inlet of the jet pump; a jet pump return line having an input coupled to an outlet of the jet pump and having an outlet adjacent the fuel pump in the first fuel storage location; and a shut-off valve operable at the outlet of the jet pump return line to selectively limit a return fuel flow provided by the jet pump and discharged from the outlet of the jet pump return line into the first fuel storage location, wherein the shut-off valve is operable to move from an open position to a closed position in response to a fuel level in the first fuel storage location surpassing a threshold, wherein the outlet of the jet pump return line is a primary outlet, the jet pump return line further including a bypass outlet that remains open to provide a restricted jet pump return flow into the first fuel storage location when the shut-off valve is in the closed position.
