In a fuel supply device disposed in a fuel tank, a pump module is constructed with at least a fuel pump, a fuel filter and a pressure regulator, and is installed in a sub-tank. A filter case of the fuel filter has first ribs and second ribs, so that an axially position between the pump module and the sub-tank is set by the first ribs, and a circumferential position therebetween is set by the second ribs. Further, a fuel inlet of a jet pump is formed in an inner bottom surface of the sub-tank, and an inner surface of the fuel inlet of the jet pump is tapered. Therefore, a fuel outlet of the pressure regulator is guided while being connected to the fuel inlet of the jet pump. Accordingly, the fuel supply device can be assembled easily.
