Abstract
A fuel tank mount for in-tank electric fuel pumps to reduce noise and vibration which includes a sealed outer shell spaced from the elongate housing of the fuel pump and supported in and isolated from the pump by resilient seals. The fuel pump and surrounding shell are supported on a fuel tank top closure. One modification utilizes a wire support. A second modification utilizes a direct mount to the top closure. A vapor by-pass is disclosed for one embodiment which closes in response to liquid fuel under pressure.
