Abstract
A fuel filter 10, constructing a supply unit 8, comprises a filter case 11 having an electric conductivity and a filter element 14. The filter case 11 is formed with an inside wall portion 11A and an outside wall portion 11B into a U shape in lateral cross section, so as to enlarge a contact area contacting with fuel in a fuel tank. The fuel discharged from the fuel pump 9 flows into a fluid chamber 15 of the fuel filter 10, and then be supplied from a fuel supply conduit 20 through a fuel flow passageway 12A to the outside. At this time, static electricity charged in the filter case 11 is discharged through its outer peripheral surface into the surrounding fuel having a slight electric conductivity.
