Safety Precautions:
* Disconnect the negative battery terminal. This is crucial to prevent accidental sparks.
* Work in a well-ventilated area. Fuel fumes are highly flammable and dangerous.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Use jack stands to securely support the vehicle. Never work under a car supported only by a jack.
* Relief the fuel system pressure. This is extremely important. The method varies slightly depending on the specific vehicle and fuel system, but generally involves disconnecting the fuel pump relay (if applicable) and starting the engine to run it until it stalls due to fuel starvation. Verify the pressure is released with a fuel pressure gauge before proceeding.
General Steps (Consult your repair manual for specifics):
1. Locate the Fuel Pump: It's typically located inside the fuel tank, though access varies. You'll likely need to drop the fuel tank.
2. Access the Fuel Tank: This usually involves removing:
* Rear seat (if necessary).
* Fuel tank straps. These will require loosening bolts. Support the tank as you remove them to prevent it from falling.
* Fuel lines (VERY IMPORTANT): You'll need to disconnect the fuel supply line and the fuel return line. Have appropriate containers ready to catch any spilled fuel. Mark the lines clearly to ensure proper reconnection.
* Electrical connectors: Disconnect any electrical connectors to the fuel pump.
3. Lower the Fuel Tank: Carefully lower the fuel tank enough to access the fuel pump. You may need a fuel tank support strap.
4. Remove the Fuel Pump Assembly: The pump is usually held in place by a retaining ring or a series of clips. Again, your repair manual will show the correct method for your specific model. You may need special tools.
5. Remove the Fuel Pump from the Assembly: The pump itself will be part of an assembly, which you will typically need to separate. This often requires some careful manipulation and may involve O-rings or seals.
6. Install the New Fuel Pump: Follow the steps in reverse order to install the new fuel pump. Ensure all O-rings and seals are properly seated.
7. Raise the Fuel Tank: Carefully raise the fuel tank and secure it back into position. Reconnect all fuel lines and electrical connectors.
8. Reconnect the Battery Terminal: Once everything is reconnected and you're satisfied with the installation, reconnect the negative battery terminal.
9. Check for Leaks: Inspect all connections for leaks before starting the car.
10. Start the Engine: Start the engine and check for any problems.
Important Considerations:
* Fuel Pump Sock/Filter: Often, the fuel pump comes with a new sock/filter. Replace this during the installation process.
* Fuel Tank Straps: Check the condition of your fuel tank straps. Replace them if they are worn or damaged.
* Professional Help: If you're uncomfortable performing this repair, consider taking your vehicle to a qualified mechanic. This is a job that can be complicated and requires attention to detail.
