How to Put a Fuel Pump on a 1994 Dodge Shadow

The Dodge Shadow was a compact car manufactured by Chrysler Corporation from 1987 to 1994. The 1994 version had a 4-cylinder 2.2-liter engine with throttle body injection. This early form of fuel injection used a relatively low fuel pressure of 15 pounds per square inch. The fuel pump in the 1994 Dodge Shadow is attached to the fuel tank, so the majority of the work in the installation of a fuel pump involves the removal of the fuel tank.

Instructions

    1

    Remove the filler cap for the fuel tank to relieve the pressure in the fuel system. Disconnect the cable for the negative battery terminal with a socket wrench to avoid unintentionally starting the engine.

    2

    Loosen the lug nuts on the right rear wheel with a socket wrench. Raise and support the the vehicle on jack stands. Remove the cap from the drain tube on the rear of the fuel tank and connect a siphon hose to the drain tube. Drain the fuel from the fuel tank into a gasoline container. Remove the filler tube for the fuel tank with a socket wrench. Remove the right rear wheel.

    3

    Detach the electrical wiring for the fuel pump and fuel sending unit. Disconnect the fuel lines for the fuel tank and support the fuel tank with a transmission jack. Loosen the mounting straps for the fuel tank and lower the fuel tank slightly with the transmission jack. Disconnect the hose on the pressure relief valve and remove the filler tube from the fuel tank. Remove the mounting straps for the fuel tank and lower the fuel tank with the transmission jack.

    Release the quick-connect fittings for the fuel lines of the fuel sender unit and disconnect the fuel lines. Remove the mounting bolts for the fuel sender unit with a socket wrench and pull the fuel sender unit from the fuel tank. Detach the electrical wiring from the fuel pump.

    5

    Remove the nut for the lower support bracket of the fuel pump. Disconnect the lower support bracket and gasket for the fuel pump. Release the clamp for the inlet hose of the fuel pump and detach the hose. Detach the fuel pump from the fuel sender unit.

    6

    Install the new fuel pump by reversing Steps 2 to 5. Fill the fuel tank and connect the cable to the batterys negative terminal with a socket wrench. Start the engine and check for fuel leaks.
