Abstract: A fuel pump module for a fuel tank in a vehicle includes a reservoir adapted to be disposed in the fuel tank and a partition disposed in the reservoir to divide the reservoir into a fuel sensing chamber and a fuel storage chamber. The fuel pump module also includes a conduit conducting return fuel from an engine of the vehicle to the fuel storage chamber of the reservoir. The fuel pump module includes a fuel pump disposed in the reservoir and having an inlet disposed in the fuel sensing chamber and an outlet disposed in the fuel storage chamber. The fuel pump module further includes a fuel usage priority valve to allow fuel from the fuel storage chamber to flow to the fuel sensing chamber to provide the inlet of the fuel pump with fuel from the fuel storage chamber.

Abstract: A modular fuel reservoir (MFR) including a cup-shaped plastic reservoir and a fuel pressure regulator supported on the reservoir. A fuel pump is supported in a tubular chamber of a retainer on top of the plastic reservoir and includes an exposed metal shell bearing against a wall of the tubular chamber and an electric motor turned on and off through a positive contact terminal and a negative contact terminal on a plastic end housing of the fuel pump. The retainer is made of an electrically conductive polymer and includes a resilient fin bearing against a metal housing of the pressure regulator. Ions stripped from the fuel and collected on the metal housing of the pressure regulator are conducted to the negative terminal on the end housing of the fuel pump through the electrically conductive retainer, the metal shell of the fuel pump, and an internal conductor in the fuel pump between the metal shell and the negative terminal.
