How to Replace a Lincoln Town Car Fuel Pump

The Lincoln Town Car was a full-size luxury car that was in production from 1980 to 2011. The fuel pump in this vehicle keeps the fuel under high pressure as required by the fuel injection system. The procedure for replacing the fuel pump is generally the same for all versions of the Lincoln Town Car made since 1998.

• Socket wrench


• Fuel pressure gauge


• Gasoline container


• Siphon hose


• Shop rag

1. Remove the cable from the negative battery terminal with a socket wrench. Open the cap on the fuel tank to relieve the fuel pressure in the tank.


2. Remove the cap from the fuel pressure relief valve on the fuel injection supply manifold.


3. Connect a fuel pressure gauge to the relief valve and place the open end of the hose of the fuel pressure gauge into a container approved for gasoline.


4. Allow the fuel in the fuel lines to drain into the container. Remove the fuel pressure gauge from the fuel pressure relief valve and replace the cap on the relief valve.


5. Place a hose into the fuel tank and siphon the fuel into the gasoline container. Clean any debris around the fuel pump with a shop rag to prevent contamination of the fuel tank when you remove the fuel pump.


6. Disconnect the fuel cell and fuel return lines from the fuel pump with a socket wrench. Detach the electrical connector from the fuel pump.


7. Remove the retaining bolts from the fuel pump module with a socket wrench. Disconnect the fuel pump and its gasket from the fuel tank.


8. Clean the mounting surface for the fuel pump with a shop rag.


9. Mount the new fuel pump and a new gasket onto the fuel tank. Fasten it into place with the retaining bolts. Torque the retaining bolts to 89 in. lbs. with a torque wrench.


10. Attach the electrical connector for the fuel pump and connect the fuel lines to the fuel pump.


11. Add at least 10 gallons of fuel to the fuel tank and check for leaks in the fuel system. Connect a fuel pressure gauge to the relief valve on the fuel injection supply manifold.


12. Attach the cable to the negative battery terminal with a socket wrench. Turn the ignition switch on for three seconds and turn the ignition off. Repeat this cycle until you pressurize the fuel system to at least 35 pounds per square inch.


13. Correct the fuel leaks and remove the fuel pressure gauge from the relief valve. Start the engine and correct the fuel leaks.
