ABSTRACT:
A fuel feed apparatus includes a grounded conductive resinous sub tank, a conductive fuel inlet pipe integrally formed with a bottom section of the sub tank and a conductive resinous jet nozzle included in a jet pump. The jet nozzle is welded on the bottom section of the sub tank, and has a nozzle port for jetting fuel. Here, the jet nozzle, the jet pump and the fuel inlet pipe are grounded via the sub tank without individual wiring member. Even if static electricity is generated due to friction between the jet nozzle and fuel jetted from the nozzle port, electrical charging can be prohibited. Thus, dielectric breakdown due to the electrically charging and cracking resulting from the dielectric breakdown can be also prohibited.
