A support shaft connects between a flange and a pump unit. An intermediate member, which connects between the support shaft and pump unit, enables a relative positional change between the support shaft and the pump unit in an axial direction of the support shaft. The intermediate member limits a relative positional change between the support shaft and the pump unit in a circumferential direction of the support shaft. A resilient member is received in the support shaft and exerts a restoring force in an axial direction of the support shaft to urge the pump unit, which is movable relative to the support shaft in the axial direction, toward a bottom portion of the fuel tank.

Fuel supply apparatus

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.

Fuel feed apparatus having inner supporting structure

In a fuel supply apparatus for a vehicle, a sender gauge is attached to a stay separated from a flange and a bracket for supporting a fuel pump. By changing the shape of the stay, without changing the shape of other components, the mounting position of the sender gauge can be arbitrarily defined. The position of the sender gauge can be moved to a position where the interference of a float member with a fuel tank, sub-tank or suction filter may be prevented.
