PROBLEM TO BE SOLVED: To provide a fuel supply device capable of accurately detecting the liquid level of a fuel in a fuel tank. SOLUTION: A level gauge 25 is positioned above a pressure regulator 24 in the vertical direction. Also, the pressure regulator 24 and the level gauge 25 are installed on both sides of a fuel pump 21 in the axial and radial directions of the fuel pump 21. Accordingly, the streamline of the excess fuel discharged from the pressure regulator 24 is deviated from the level gauge 25 and the fuel discharged from the pressure regulator 24 does not directly strike the level gauge 25. Thus, the level gauge 25 can be prevented from mis-operating, and increase detection accuracy for the level of the fuel in the fuel tank 2. In addition, the fuel discharged from the pressure regulator 24 is limited to flow by a tube part 15, and accumulated near a suction filter 23. As a result, the fuel pump 21 can suck the fuel to the end. COPYRIGHT: (C)2005,JPO&NCIPI |
