WARNING:
- This procedure involves fuel handling. Be prepared for spillage at all times and always observe fuel handling precautions. Failure to follow these instructions can result in personal injury.
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.
- Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.

1. Release the fuel system pressure.
2. Disconnect the battery ground cable.







3. Release the fuel tank filler cap and position aside.







4. Insert a suitable fuel drain tube into the fuel tank filler pipe until it reaches the fuel tank inlet tube.

5. CAUTION: The fuel pump (FP) module and the fuel level sensor will be below the fuel level in the tank when the tank is full. Make sure to drain 1/8 of the fuel capacity through the filler pipe prior to removing the FP module or fuel spillage will occur.

NOTE: When draining a completely full fuel tank, this step will remove approximately 1/8th of fuel from the LH side of the fuel tank.

Attach the fuel storage tanker to the fuel drain tube and remove as much fuel as possible from the fuel tank filler pipe.

6. Remove the rear seat cushion.
7. Position any insulation padding covering the FP module access cover aside.







8. Remove the FP module access cover and position aside.







9. NOTE: 4.0L and 4.6L fuel pump (FP) module shown, 5.4L similar.

Disconnect the FP module electrical connector.







10. NOTE: Place absorbant pads in the general work area in case of fuel spillage.

Disconnect the rear fuel supply tube-to-FP module quick connect coupling.







11. Using the special tool, remove the FP module retaining lock ring.







12. Position the FP module aside. Using the fuel storage tanker and a suitable fuel drain tube, completely drain the LH side of the fuel tank.

13. CAUTION: The fuel pump (FP) module must be handled carefully to avoid damage to the float arm, filter and the convolute hoses.

Carefully lift the FP module out of the fuel tank enough to access the fuel cross over tube-to-FP module quick connect coupling.







14. Disconnect the fuel cross over tube-to-FP module quick connect coupling.

15. CAUTION: The fuel pump (FP) module must be removed and handled carefully to avoid damage to the float arm.

Completely remove the FP module from the fuel tank.







16. Insert a suitable fuel drain tube into the cross over fuel tube quick connect coupling.
17. Attach the fuel storage tanker to the fuel drain tube and completely drain the remainder of the fuel from the RH side of the fuel tank.
