To supply a fuel of sufficient quantity to an engine even when small amount of the fuel is left in a tank by providing an oil feed pipe to lead the fuel into the tank in a fuel tank, and connecting an outlet end part of the oil feed pipe to the reservoir so that a part of the fuel flowing in the oil feed pipe directly flows in the reservoir.

In a fuel tank 10 for automobile, a reservoir 12 of small capacity to which an oil feed pipe 60 is connected is arranged in a tank body, a center area 20 at a bottom part 18 of the reservoir 12 is formed deepest, and an electric fuel pump 26 is arranged in the center area 26. A pressure regulator 30 from which a return pipe 32 is branched is interposed in the middle of a discharge pipe 28 of the fuel pump 26, and a drive nozzle 36 of a suction jet pump 38 is equipped on a discharge end part of the return pipe 32. The suction jet pump 38 is provided with a capture nozzle 40 to form a flow-in end part of an overflow pipe 42, the overflow pipe 42 is arranged to be extended in an approximately perpendicular manner, and opened at the level below an upper boundary edge part of the reservoir 12.
