Abstract
Surplus fuel returns from an engine into the sub-tank through a bellows pipe. A downstream end of the bellows pipe is supported by a sub-tank lid that closes an opening of a sub-tank. One ends of arms engage with the top of a pump module, which includes a fuel pump. The other ends of arms engage with the outer peripheral wall of the sub-tank. Thereby, the arms connect between the pump module and the sub-tank. Surplus fuel flows into the sub-tank through the bellows pipe, and strikes against the arm. Thereby, return fuel, which comes back into the sub-tank, decreases in kinetic energy. Thus, sound and vapor generated from fuel in the sub-tank can be reduced when return fuel comes back into the sub-tank.
