I. Preparation:
1. Safety First: Disconnect the negative battery cable. Let the vehicle sit for at least 15 minutes to allow any residual charge to dissipate. Wear safety glasses and gloves. Work in a well-ventilated area.
2. Gather Tools and Materials: You'll need a variety of tools, including but not limited to:
* Socket set (metric) with extensions and ratchets
* Wrenches (metric)
* Screwdrivers (Phillips and flathead)
* Fuel pump pliers (or similar tool to disconnect fuel lines)
* Fuel line disconnect tool (highly recommended to avoid leaks)
* Torque wrench
* Jack and jack stands (essential for safety)
* New fuel pump assembly (ensure it's the correct one for your vehicle)
* Shop rags
* Safety glasses and gloves
* Drain pan
* Fuel line clamps (if necessary)
3. Locate the Fuel Pump: The fuel pump is usually located inside the fuel tank, requiring tank removal or access through a dedicated access panel. Consult your repair manual for the exact location and method of access. Some models might require dropping the fuel tank.
II. Fuel Tank Access and Removal (If Necessary):
1. Lower the Fuel Tank: If required, safely raise and support the vehicle using jack stands. Locate the fuel tank straps and carefully loosen and remove them. You might need to disconnect various electrical connectors and fuel lines.
2. Drain the Fuel Tank: Carefully drain the fuel tank using a siphon pump or by removing the fuel filler neck. Dispose of the fuel properly; it's illegal to dump it.
III. Fuel Pump Replacement:
1. Access the Fuel Pump: Once the tank is lowered (or if accessing through an access panel), you should see the fuel pump assembly. It's typically secured by bolts or a retaining ring.
2. Disconnect Fuel Lines and Electrical Connections: Carefully disconnect the fuel lines using fuel line pliers or a disconnect tool. This step is critical to avoid leaks. Use a shop rag to absorb any spilled fuel. Disconnect the electrical connectors as well.
3. Remove the Fuel Pump: Remove the fuel pump retaining bolts or ring and lift the assembly out of the tank.
4. Install New Fuel Pump: Carefully compare the new fuel pump to the old one and install it according to the manufacturer's instructions. Make sure the new o-rings and gaskets are properly seated.
5. Reconnect Fuel Lines and Electrical Connections: Reconnect the fuel lines and electrical connectors securely. Use new clamps if necessary.
IV. Reassembly and Testing:
1. Raise the Fuel Tank (if applicable): Carefully raise the fuel tank back into its position and secure it with the straps.
2. Reconnect all components: Reconnect all fuel lines, electrical connections, and any other components removed during the process.
3. Lower the Vehicle (if applicable): Lower the vehicle safely.
4. Reconnect the Battery Cable: Carefully reconnect the negative battery cable.
5. Test the Fuel System: Turn the ignition key to the "ON" position (don't crank the engine) to check for the fuel pump's priming sound. If you hear it, start the engine and check for leaks. Let the engine run for a few minutes to ensure everything works correctly.
Important Considerations:
* Repair Manual: A detailed repair manual specific to your 2000 Ford Expedition is invaluable. It provides precise diagrams, torque specifications, and step-by-step instructions.
* Safety: Fuel is highly flammable. Take all necessary safety precautions to avoid accidents.
* Professional Help: If you're not comfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic.
This is a general guide and may not cover all specific details for your vehicle. Always refer to a repair manual for your specific year and engine for accurate instructions and safety precautions. Incorrect installation can lead to serious damage to your vehicle.
