A cosmetically attractive fuel tank assembly preferably for a motorcycle application has a fuel pump subassembly inserted into the fuel chamber of the tank through bottom access hole thus preserving the overall appearance of the tank itself. The flange of the fuel pump subassembly covers the bottom access hole and sealably months to a bottom wall of the fuel tank. Various fuel pump subassembly components, such as a fuel pressure regulator, an outlet fuel filter, an electrical connector and a fuel outlet mount directly to the flange along with a tripod like vibration absorbing bracket which supports the fuel pump and preferably a fuel level sensor. The bracket is flexible and resiliently contacts an internal surface of a bottom wall of the fuel tank via a resilient pad, and is threadably engaged to the flange and spaced therefrom by a vibration damping member.
