Abstract
A fuel supply system includes a fuel pump configured to pump fuel from a first fuel storage location to an engine. A jet pump is 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 has an inlet in fluid communication with an outlet of the fuel pump and has an outlet coupled to an inlet of the jet pump. A jet pump return line has an input coupled to an outlet of the jet pump and has an outlet adjacent to the fuel pump. A shut-off valve operates to selectively limit fuel flow through the jet pump return line.
