Removal and Installation

WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

WARNING: 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 component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.

WARNING: When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury.

WARNING: Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

All vehicles

20. NOTICE: The Fuel Pump (FP) module must be handled carefully to avoid damage to the float arm.

NOTE: The FP (Fuel Pump) module will have residual fuel remaining internally, drain into a suitable container.
Completely remove the FP (Fuel Pump) module from the fuel tank.


21. NOTE: Inspect the surfaces of the FP (Fuel Pump) module flange and fuel tank O-ring seal contact surfaces. Do not polish or adjust the O-ring seal contact area of the fuel tank flange or the fuel tank. Install a new FP (Fuel Pump) module or fuel tank if the O-ring seal contact area is bent, scratched or corroded.
Remove and discard the FP (Fuel Pump) module O-ring seal.


22. NOTE: Make sure to install a new FP (Fuel Pump) module O-ring seal.

NOTE: To install, apply clean engine oil to the O-ring seal.

To install, reverse the removal procedure.
