摘要： A fuel pump mounting structure has an opening in a side surface or a bottom surface of a fuel tank. A fuel pump assembly including a cylindrical pump body and a filter connected to a suction side of the pump body is accommodated in a space located inside of the opening. A flange section of a housing that encloses the pump body engages an outside surrounding area of the opening. A mounting plate covers the outside of the flange section. The fuel pump assembly is fixed to the opening through the flange section and the mounting plate. The axis of the pump body extends generally parallel to a mounting surface of the mounting plate, and the pump body and the filter overlap each other relative to a position in a direction of the axis. The mounting structure reduces the moment against the mounting plate, reliably supports the fuel pump under a stable condition without requiring a large and rigid construction, and improves the seal with the fuel tank.
