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 body 10A, a one side closing member 10B and an other side closing member 10C. The wire mesh cylindrical body 10 is arranged in a cup body S, and also the one side closing member 10B is arranged to be abutted on the cup body S. A fuel return passage 24 is opened in the inside of the wire mesh cylindrical body 10A through the other side closing member 10C and also placed to the one side closing member 10B.
