Abstract
A noise from a fuel pump module is reduced by housing a port injection (PI) fuel pump in a pump case of a fuel tank, in a structure in which the PI fuel pump is held with a bracket that is provided at a position between the PI fuel pump and a PI suction filter. The PI fuel pump and the bracket that engages with the pump case are interposed by an elastic member that abuts a base part of the bracket. In operation, when the PI fuel pump transmits its vibration to the pump case through the elastic member and the bracket, the elastic member dampens and reduces the vibration transmitted to the bracket, thereby reducing the noise by a reduction of transmitted vibration through the pump case to a subtank and the fuel tank.
