Step 1: Gather Required Tools and Materials

Before you begin, make sure you have the following tools and materials ready:

Practical Tips

• Always work in a well-ventilated area to avoid inhaling gasoline vapors.
• Wear safety goggles and gloves to protect yourself from harmful substances.

Step 2: Relieve Fuel System Pressure

1. Locate the fuel pump fuse in the fuse box and remove it. This will prevent the fuel pump from activating.
2. Start the engine and let it run until it stalls. This will relieve pressure in the fuel lines.
3. Turn off the ignition and disconnect the negative battery terminal to ensure safety during the process.

Step 3: Remove the Fuel Tank

1. Safely lift the vehicle using a jack and secure it with jack stands.
2. Disconnect the fuel lines using the fuel line disconnect tool.
3. Remove the bolts securing the fuel tank using the socket set.
4. Carefully lower the tank and set it aside.

Step 4: Access the Fuel Pump

1. Once the tank is removed, locate the fuel pump assembly on the top of the tank.
2. Remove the retaining ring that holds the fuel pump in place. This may require a special tool or a flathead screwdriver.
3. Disconnect any electrical connectors and fuel lines attached to the pump.

Step 5: Install the New Fuel Pump

1. Carefully remove the old fuel pump from the assembly.
2. Install the new fuel pump into the assembly, ensuring it is seated correctly.
3. Reconnect the electrical connectors and fuel lines to the new pump.
4. Replace the retaining ring to secure the new pump in place.

Step 6: Reinstall the Fuel Tank

1. Lift the fuel tank back into position under the vehicle.
2. Reattach the bolts that secure the tank, ensuring they are tightened to the manufacturer’s specifications.
3. Reconnect the fuel lines, making sure they are secure.

Step 7: Restore Fuel System Pressure

1. Reinsert the fuel pump fuse back into the fuse box.
2. Reconnect the negative battery terminal.
3. Turn the ignition to the "On" position (without starting the engine) to prime the fuel system. Check for any leaks.

Conclusion

Congratulations! You have successfully replaced the fuel pump in your Chevrolet Corvette C5 Z06. Remember to check for leaks before starting the engine.
