Here's a general outline. This is NOT a comprehensive guide and should not be used as the sole source of information. You should consult a repair manual specific to your 1995 Mercury Villager for detailed instructions, torque specifications, and diagrams. A Haynes or Chilton manual is a good investment.
Safety First:
* Disconnect the negative battery terminal before starting any work.
* Work in a well-ventilated area. Fuel fumes are highly flammable.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Dispose of old fuel properly. Don't pour it on the ground.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Torque wrench
* Fuel line disconnect tools
* Screwdrivers (Phillips and flathead)
* Pry bar (plastic is preferable to avoid scratching)
* Jack and jack stands
* Wheel chocks
* Fuel pump pliers (may be needed to remove the retaining ring)
* New fuel pump (ensure it's the correct part for your vehicle)
* New fuel filter (recommended)
* Shop rags
* Safety glasses and gloves
General Steps (Consult your repair manual for precise details):
1. Prepare the vehicle: Park on a level surface, engage the parking brake, and chock the wheels. Raise and securely support the vehicle on jack stands.
2. Access the fuel pump: This usually involves dropping the fuel tank. The location of the fuel pump varies slightly depending on the engine configuration. You may need to remove the spare tire, access panel(s), and potentially the exhaust system (partially or completely) to reach the tank. Refer to your repair manual for the specifics.
3. Drain the fuel tank: This is crucial to reduce the amount of fuel you're working with. Use a siphon pump to safely remove the fuel. Again, dispose of the fuel properly.
4. Disconnect fuel lines and electrical connections: Carefully disconnect the fuel lines using the appropriate disconnect tools. There will likely be a fuel pressure regulator attached – be mindful of how it connects. Disconnect the electrical connector to the fuel pump.
5. Lower the fuel tank: Carefully lower the fuel tank. This may involve removing straps, bolts, or other fasteners. Support the tank as you lower it to prevent damage.
6. Remove the fuel pump assembly: The fuel pump is typically accessed through a large access hole in the top of the tank. You may need to remove a retaining ring or cover to access the pump itself.
7. Install the new fuel pump: Carefully install the new fuel pump assembly, ensuring it's properly seated and the retaining ring is secure.
8. Reassemble everything: Reinstall the fuel tank, reconnect the fuel lines and electrical connectors, and reattach any removed components.
9. Reconnect the battery: Reconnect the negative battery terminal.
10. Prime the fuel system: You may need to prime the fuel system before starting the engine. This might involve using the ignition switch (several on-off cycles) or a specific priming tool.
11. Check for leaks: Inspect all connections for leaks before starting the engine.
12. Start the engine: Start the engine and check for proper operation. Listen for any unusual noises from the fuel pump.
