Abstract
A fuel feeder comprises a filter case installed in a fuel tank through a fuel-tank access hole by means of a mounting bracket. An in-tank fuel pump and a filter element are both disposed in the filter case, while a fuel-pressure regulator having a fuel return port is mounted on the upper side of the filter case. Also provided is a fuel return pipe connected at its upstream end to the fuel return port of the pressure regulator, and having a conduit portion extending downwards from the upstream end along the outer periphery of the filter case. The fuel return pipe has a return-fuel outlet formed at a side of the conduit portion facing the outer periphery of the filter case, whereby superfluous fuel returned from the pressure regulator flows into the tank at a position spaced apart from the bottom of the tank with impingement of the superfluous fuel flow against the outer periphery of the filter case to reduce noises and to effectively release static electricity from the electrified filter case.
