PROBLEM TO BE SOLVED: To improve discharge performance by preventing vapor included in return fuel from being absorbed again into a fuel pump, to prevent occurrence of noise accompanied by return fuel injection to the inside of the fuel tank, and to prevent temperature rise in the fuel tank. SOLUTION: Fuel in the fuel tank is pressurized by the fuel pump, and also fuel regulated to a constant pressure by a pressure, regulator is supplied to a fuel injection valve. Return fuel in the pressure regulator is made to flow back into the inside of the fuel tank through a return fuel passage. A wire mesh cylindrical body 10 comprises a wire mesh cylindrical part 10C whose both ends are opened by an upper opening part 10A and a lower opening part 10B, and an upper side closing member 10D for closing the upper opening part 10A. The wire mesh cylindrical body 10 is arranged in the inside of a cup body S, and also the lower opening part 10B is fitted around a positioning cylindrical projected part SA arranged on the cup body S so as to close the body 10. The return fuel passage 24 is opened in the inside of the wire mesh cylindrical part 10C through the upper side closing member 10D and also placed oppositely to the projected end surface SC of the positioning cylindrical projected part SA.
