Beschreibung
Zusammenfassung:	A fuel system for fluidly connecting a fuel tank with an engine includes a low-pressure fuel circuit connected to the fuel tank. A high-pressure fuel circuit connected to the engine is supplied with fuel by the low-pressure fuel circuit. A priming fuel circuit includes a priming fuel conduit and a priming valve. The priming fuel conduit has a first segment and a second segment. The priming valve has an inlet and an outlet. The first segment of the priming fuel circuit interconnects the low-pressure fuel circuit and the outlet of the priming valve. The second segment of the priming fuel circuit interconnects the high-pressure fuel circuit and the inlet of the priming valve. The priming valve is operable to control a flow of fluid through the priming fuel conduit to thereby selectively connect and disconnect the high-pressure fuel circuit and the low-pressure fuel circuit.
