Step-by-Step Installation Guide
Step 1: Safety First
Before you begin, ensure you are working in a well-ventilated area. Wear safety goggles and gloves to protect yourself from fuel and debris.
Step 2: Relieve Fuel System Pressure
To safely replace the fuel pump, relieve the fuel system pressure. Locate the fuel pump fuse in the fuse box and remove it. Start the engine and let it run until it stalls. This will relieve any remaining pressure in the fuel lines.
Step 3: Remove the Fuel Tank
Next, you will need to remove the fuel tank to access the fuel pump. Follow these steps:
- Disconnect the negative battery terminal.
- Support the fuel tank with a jack or stand.
- Unbolt the fuel tank straps and lower the tank carefully.
- Disconnect the fuel lines and electrical connectors from the tank.
Step 4: Access the Fuel Pump
Once the tank is removed, locate the fuel pump assembly. Remove the retaining ring or screws holding the pump in place and carefully lift the pump out of the tank.
Step 5: Install the Walbro Fuel Pump
Now it’s time to install the Walbro fuel pump. Follow these steps:
- Remove the old fuel pump from the assembly.
- Install the new Walbro pump into the assembly, ensuring it is properly seated.
- Reattach any necessary components, such as the fuel filter and sock.
- Secure the pump with the retaining ring or screws.
Step 6: Reinstall the Fuel Tank
With the new pump installed, carefully reinstall the fuel tank. Make sure to:
- Reconnect the fuel lines and electrical connectors.
- Secure the fuel tank with the straps.
- Double-check that everything is connected properly.
Step 7: Reconnect the Battery and Test
Reconnect the negative battery terminal. Before starting the engine, turn the ignition to the “ON” position without starting it. This will prime the fuel system. Check for any leaks around the fuel lines and pump area.
Step 8: Start the Engine
Finally, start your Celica GT-Four. Monitor the engine for any irregularities and ensure that the fuel pump is functioning correctly. Take your car for a test drive to experience the improved performance!
