Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Access Fuel Pump

Tools Required: Socket set, screwdrivers
Remove the back seat (if the fuel pump access is under the seat) or the trunk floor panel (if accessing from the trunk).
Locate the fuel pump access cover and remove it.

3. Remove Fuel Pump

Tools Required: Fuel line disconnect tool, wrench set
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines using the fuel line disconnect tool.
Remove the electrical connector from the fuel pump.
Unscrew and carefully remove the fuel pump assembly from the tank.

4. Inspect and Replace

Inspect the old fuel pump for signs of wear or damage.
If necessary, replace the fuel pump with a new one. Ensure the new pump is compatible with the 2007-2011 Toyota Camry XV40.
Reinstall the fuel pump assembly back into the tank, ensuring it is seated properly.

5. Reconnect Components

Reconnect the electrical connector to the fuel pump and reattach the fuel lines securely.
Replace the fuel pump access cover and reinstall the back seat or trunk floor panel.

6. Final Checks

Reconnect the negative battery terminal.
Reinstall the fuel pump fuse and turn the ignition to the "ON" position (without starting the engine) to prime the fuel system.
Check for leaks around the fuel lines and pump.
