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. The wall of the tubular chamber on retainer constitutes a shield around the fuel pump which reduces radiated electrical emissions attributable to commutation in the electric motor of the fuel pump.
