Fuel Pump Module
WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
The electric fuel pump is located in the fuel tank and is part of the fuel pump module. See Figure . The fuel system uses either a positive displacement, gerotor type immersible pump with a permanent magnet electric motor. This fuel system dose not contain the traditional fuel return lines. The regulator contains a calibrated spring which forces a diaphragm against the fuel filter return port. When pressure exceeds the calibrated amount, the diaphragm retracts, allowing excess pressure and fuel to vent into the tank. The fuel pump has a maximum deadheaded pressure of approximately 130 psi (880 kPa). The regulator adjusts fuel system pressure to approximately 53-63 psi (365-434 kPa).
