Abstract
The intermediate part is fixed between the unit case body, which integrally houses the fuel pump and the filter element, and the unit case supporting flange, which hangs the pump unit from the upper wall of the fuel tank. A height Ha of the intermediate part is set to correspond to a height difference between a height Ht of the fuel tank and the sum of a height Hb of the unit case body and a height Hc of the unit case supporting flange. The wall is arranged in the proximity of the lower end of the intermediate part to make a fuel channel formed below the wall small and avoid generation of air stagnation in the fuel channel.
