WARNING: Working with fuel systems can be dangerous. Ensure that you take proper safety precautions, including working in a well-ventilated area, keeping the vehicle away from heat sources, and avoiding sparks or open flames. It's also recommended to disconnect the battery before starting the repair.
Tools and Supplies Needed:
- Jack and jack stands
- Wheel chocks
- Shallow drain pan
- Phillips screwdriver
- Flat-blade screwdriver or pry tool
- Fuel injector removal tool (if applicable)
- Replacement fuel pump assembly (with fuel filter sock and rubber gasket)
- New fuel line clamps (if applicable)
- Gasoline (for refilling the tank)
Procedure:
1. Prepare the Vehicle: Engage the parking brake, chock the wheels, and jack up the vehicle until the rear wheels are off the ground. Support the vehicle with jack stands at appropriate locations.
2. Locate the Fuel Pump Assembly: Open the trunk of the vehicle. Inside the trunk, beneath the carpet lining, you'll usually find a small access panel secured by screws or clips. Remove this panel to access the fuel pump assembly.
3. Disconnect the Fuel Line: Disconnect the fuel line from the fuel pump assembly. There may be a fuel line clamp that needs to be released. Be cautious as some fuel might leak out during disconnection.
4. Remove the Electrical Connector: Locate the electrical connector for the fuel pump. Press down on the connector's release tab and disconnect it from the fuel pump assembly.
5. Remove the Fuel Pump Assembly: Remove the lock ring or collar that holds the fuel pump assembly in place. You might need a flat-blade screwdriver or a pry tool for this. Be careful not to drop any parts into the fuel tank.
6. Extract the Fuel Pump: Gently lift and extract the fuel pump assembly out of the fuel tank. This might require some maneuvering to clear any obstructions.
7. Replace the Fuel Filter Sock: If the fuel pump assembly includes a separate fuel filter sock, remove the old sock and install a new one onto the new pump assembly.
8. Install the New Fuel Pump Assembly: Place the new fuel pump assembly into the fuel tank, ensuring that the o-ring or gasket is properly seated. Fasten the assembly with the lock ring or collar.
9. Reconnect the Electrical Connector: Reconnect the electrical connector to the new fuel pump assembly.
10. Reconnect the Fuel Line: Reattach the fuel line to the fuel pump assembly and secure it with the fuel line clamp if necessary.
11. Replace the Access Panel: Reinstall the access panel back onto the trunk floor, ensuring it's securely fastened.
12. Lower the Vehicle: Slowly lower the vehicle using the jack until the wheels are back on the ground.
13. Start the Engine: Once you've reconnected the fuel lines and confirmed that everything is properly secured, you can start the engine to test the new fuel pump.
14. Check for Leaks: Inspect the area around the fuel pump assembly and fuel lines for any leaks. If there are any leaks, tighten the connections appropriately.
15. Reinstall the Interior: Put back any interior panels, carpeting, or covers that you might have removed during the process.
Refuel the Vehicle: Add fuel to the vehicle if needed. Remember to follow proper fuel handling guidelines and safety precautions.
Note: It's always a good practice to refer to the specific service manual or repair guide for your vehicle model for more accurate instructions and any additional steps that might be specific to your Toyota Camry.
