To provide a miniaturizable fuel supply device for easily installing a fuel filter in a fuel tank.
The fuel filter 20, a fuel pump 10 and a pressure regulator 40 are detachably installed. A filter case 21 of the fuel filter 20 is composed of an upper case 22 and a lower case 31. The upper case 22 and the lower case 31 are welded by a boundary part 29. The boundary part 29 is positioned in the fuel tank 1. The upper case 22 and the lower case 31 are respectively integrally molded except for a connecting pipe 37, and a cover part 25 is fitted to the fuel tank. Thus, since the number of part items is reduced by dispensing with the other member for installing the fuel filter 20 in the fuel tank 1, installation and removal man-hours are reduced, and manufacturing cost can also be reduced.
