Beschreibung
Zusammenfassung:	A fuel system for an internal combustion engine, the fuel system including a fuel tank, a fuel pump communicating with the fuel tank, a fuel manifold downstream of the fuel pump, and a return line downstream of the fuel pump, the return line communicating with the fuel tank. The fuel system also includes a self-relieving fuel filter assembly having a filter member. The self-relieving fuel filter assembly communicates with the return line and is variable between a first state, wherein fuel passes through the return line and the filter member before returning to the fuel tank, and a second state, wherein fuel passes through the return line without passing through the filter member before returning to the fuel tank. The self-relieving fuel filter assembly therefore permits the continuous passage of fuel through the return line even when the filter member becomes plugged.
