ABSTRACT:
A low-pressure fuel filter is disposed in a fuel-return pipe from the fuel pressure regulator. In a portion of the fuel-return pipe between the fuel pressure regulator and a fuel element of the low-pressure fuel filter, a bypass device which includes, for example, a jet pump or an aperture may be provided so that fuel can flow back to the fuel tank, bypassing the fuel filter when the fuel filter is blocked.
