Solution

1. Preparation

Tools Required:
- Fuel line disconnect tool
- 10mm socket and ratchet
- Screwdriver set
- Clean rags
- Safety glasses
- Gloves
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Relieve Fuel System Pressure

Locate the fuel pump relay in the fuse box.
Remove the fuel pump relay and start the engine, allowing it to run until it stalls (this relieves pressure in the fuel lines).
Turn off the ignition and reconnect the relay.

3. Access the Fuel Filter

Locate the fuel filter; it is usually found along the fuel lines near the fuel tank or under the vehicle.
Disconnect the fuel lines using the fuel line disconnect tool. Be cautious as residual fuel may spill.
Remove any brackets or screws securing the fuel filter using the 10mm socket.

4. Remove and Replace the Fuel Filter

Carefully remove the old fuel filter from the mounting bracket.
Install the new fuel filter in the same orientation as the old one, ensuring the flow direction matches (usually marked on the filter).
Secure the fuel filter with the bracket and screws.

5. Reconnect Fuel Lines

Reconnect the fuel lines, ensuring they are fully seated and secure.
Reinstall any protective covers or shields removed during the process.

6. Final Steps

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine to pressurize the fuel system. Check for leaks around the fuel filter and lines.
Start the engine and allow it to idle while checking for proper operation.
