Abstract
In a fuel tank, a pressure regulator is placed at an outside of a sub-tank and regulates a pressure of fuel of a pressure-regulation path, which is discharged from a fuel pump and is fed toward an outside of the fuel tank. A fuel recovery passage portion recovers excess fuel, which becomes excess at the pressure-regulation path, to the sub-tank. The sub-tank has an opening at a location that is higher than the suction filter. The fuel recovery passage portion is inserted from the outside of the sub-tank into the inside of the sub-tank through the opening while a gap is formed between the fuel recovery passage portion and the opening, so that the fuel recovery passage portion has an excess fuel outlet that discharges the excess fuel at a location that is on an inner side of the opening where an inside of the sub-tank is placed.
