ABSTRACT:
The automotive fuel pump module includes a sealed housing containing a fuel reservoir and a fuel pump for mounting within the fuel tank of a vehicle. A flange is secured to the wall of the fuel tank and lies in communication with the outlet of the fuel pump by a pair of pivotally connected arms for flowing fuel from the reservoir within the housing to outside of the fuel tank and to the fuel rail. A torsion spring biases the arms such that the reservoir body is referenced to the bottom of the fuel tank from the flange of the module. A pressure regulator may be provided within the housing for returning excess fuel to the reservoir. A mounting cup includes a pocket for receiving a pin on the housing cover for vibrationally isolating the pump and housing from one another and preventing rotation of the pump relative to the housing.
