PROBLEM TO BE SOLVED: To form a fuel supply system provided with a filter and a pressure regulator compact, and reduce its manufacturing cost. SOLUTION: One end K4 of a pump case K is closed by a pump housing 1 forming a pump chamber 4 and a pump cover 2, and the other end K2 is closed by a bearing holding cover 3 to form a motor chamber 8 in the pump case K. Impellers 25 disposed in the pump chamber 4 are driven by a motor M disposed in the motor chamber 8. With the bearing holding cover 3, a fuel chamber 10B of the pressure regulator R is integrally formed, and a rotation shaft 22 of the motor M is rotatably supported by the bearing holding cover 3 and the pump housing 1. In the motor chamber 8 around the motor M, the cylindrical filter F is disposed to form a filtration chamber A, and a delivery passage 9 is opened from the filtration chamber A outward.
