Abstract
A cover for a fuel tank opening is molded with insulating resin and a plurality of terminal pins is directly inserted thereinto. A lower housing portion, made of conductive resin and containing a fuel filter element, is weld-connected to the fuel tank side of the cover. A fuel pump is held under the cover. When electricity is supplied to the fuel pump via an electric connector, fuel is discharged from the fuel pump and this discharged fuel is filtered by a fuel filter. Static electricity generated in the fuel filter dissipates through the lower housing portion made of conductive resin. This construction enables suppression of electrostatic voltage generated in the fuel filter. Moreover, a plurality of connector terminals are directly inserted into the upper housing cover portion of the fuel filter housing at the time of molding, which can therefore supply electric power to the fuel pump with a simplified construction.
