How to Change the Fuel Pump in a 1993 Dodge Spirit

The Dodge Spirit is a mid-size sedan manufactured from 1989 to 1995. Most 1993 models have a four-cylinder, 2.5-liter engine that uses throttle-body injection, or TBI. TBI is an early form of fuel injection developed in the 1980s that used low fuel pressure, typically in the range of 10 to 15 pounds per square inch. The fuel pump on the 1993 Dodge Spirit is integrated with the fuel sender into a single unit. The replacement of the fuel pump on this vehicle requires you to disconnect the fuel tank.

Instructions

1

Disconnect the cable to the batterys negative terminal with a socket wrench to prevent an accidental spark from the battery. Drain the fuel in the fuel tank by siphoning the fuel into a gasoline container. Raise the vehicle with a jack, and support it on jack stands. Remove the fuel tank from the vehicle. Squeeze the retainer tabs on the fuel supply line and fuel return lines. Disconnect these fuel lines from the fuel pump module.

2

Remove the mounting bolts from the fuel pump module with a socket wrench. Disconnect the wiring on top of the fuel pump module, and remove the nut for the fuel pumps lower bracket with a socket wrench. Remove the hose clamp from the fuel pump, and disconnect the outlet hose from the fuel pump. Remove the clamp for the inlet hose on the fuel pump, and disconnect the inlet hose.

3

Tilt the fuel pump to avoid damage to the float arm and fuel filter. Remove the lower gasket. Remove the fuel pump from the faceplate of the fuel tank. Remove the lower bracket and upper gasket from the fuel pump.

4

Place the new upper gasket onto the new fuel pump. Connect the fuel pump to the upper bracket and outlet hose. Attach the hose clamp to the outlet hose. Place the new lower gasket into the lower bracket, and fasten the bolt for the lower bracket with a socket wrench. Connect the inlet hose to the fuel pump, and attach its hose clamp. Connect the electrical wiring for the fuel pump.

5

Install the fuel pump module so the filter on the fuel pump module fits into the tray on the fuel tank. Align the bottom gasket so its holes align with the corresponding holes on the fuel tank. Attach the fuel pump module to the fuel tank by tilting it as necessary to clear the float arm and fuel filter. Use a socket wrench to fasten the fuel pump module to the fuel tank with the mounting bolts.

6

Connect the fuel supply line and fuel return line to the fuel pump module. Install the fuel tank, and lower the vehicle. Fill the fuel tank with fuel, and connect the cable for the batterys negative terminal with a socket wrench. Start the engine, and check for fuel leaks.
