PROBLEM TO BE SOLVED: To provide a fuel system allowing the components of the fuel system to be arranged compactly on the module system. SOLUTION: A fuel pump 12 is composed of a pump part 14 and a brushless motor 1 to drive the pump. The housing 15 of the fuel pump 12 includes a cylindrical motor housing 15a so formed that the stator 16 of brushless motor 13 is molded with an insulating resin and a mounting flange 27 for fixing the fuel pump 12 to a fuel tank is formed integrally at the top of the motor housing 15a. The drive circuit 26 for the brushless motor 13 is molded from the same resin material used to the stator 16 in such a way that the drive circuit 26 is sealed at the same time. A pressure regulator 44 to adjust the discharge pressure of the pump part 14 and a fuel filter 40 formed from a fibrous molding material having excellent filtrating performance are assembled under the pump part 14 of the fuel pump 12, and the fuel filtrated by the filter 40 is sucked into the fuel pump 12.
