Abstract
A fuel supply apparatus for engines of a multi-point injection system using fuel tanks of many sizes and shapes is disclosed. In the fuel supply apparatus, a pump device 10 is constructed of an electric motor-driven fuel pump 10, a fuel filter 49, and a pressure regulator 21, which are contained in a housing integrally constructed of a first and second cases 11 and 12. A suction port 15 of the pump device 10 communicates with a suction opening 24 of the fuel pump 19, while a discharge outlet portion 26 of the pump device 10 communicates with a discharge port 17 through the fuel filter 49. The discharge port 17 communicates with an inlet of the pressure regulator 21. An outlet of the pressure regulator 21 communicates with a return port 16 of the pump device 10.
