PROBLEM TO BE SOLVED: To improve loading property onto a two wheeler and improve mounting workability by arranging a fuel pump, a strainer, and a pressure regulator in a single case integrally in advance. SOLUTION: A pump storage chamber 10 is formed by a bottomed cup-like pump body 1 and a pump cover 4, and the fuel pump P provided with the strainer S connected with a pump suction passage Pa is arranged in the pump storage chamber 10. The fuel pump P is supported by a locking step part 1c of the pump cover 4 and the pump cover 4, a fuel suction hole 2 communicated with a fuel tank T is opened into a fuel flowing-in chamber 19 in which the strainer S is arranged, and a pump discharge passage Pb is communicated with a fuel discharge hole 7 provided in the pump cover 4. The pressure regulator R is stored and arranged in a regulator storage chamber 6 of the pump cover 4, and a regulator fuel flowing-in hole 12 is communicated with the fuel discharge hole 7 through a regulator fuel flowing-in passage 8. A regulator fuel discharge hole 16 is communicated with an annular fuel chamber 23 through the regulator storage chamber 6, and the annular fuel chamber 23 is communicated with the fuel tank T through a fuel discharge hole 3.
