Abstract:
A fuel delivery system and method are described that can provide different pressures of the supply of fuel to a power source such as an engine or a motor. The engine or the motor can power, for example, a vehicle or a generator. The fuel delivery system includes a fuel supply line to deliver fuel from a fuel tank to the engine or motor. A fuel pump outlet line delivers fuel from the tank to the fuel supply line. An in-tank return line returns fuel from a fuel return line to the tank. A regulator connects with the fuel pump outlet line to maintain a pressure of the fuel pump outlet line at or below a pressure set-point of the regulator. A solenoid valve connects with the in-tank return line such that a set-point pressure of the regulator is utilized when the solenoid valve closes the in-tank return line.
