Solution

1. Preparation

Gather tools and parts: OBD-II scanner, fuel pressure gauge, socket set, new fuel filter, safety goggles, and gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Disconnect Battery

Disconnect the negative terminal of the battery to prevent electrical shocks.
Use a wrench to loosen the terminal clamp and remove it.

3. Relieve 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 to relieve pressure in the fuel lines.

4. Remove the Old Fuel Filter

Identify the location of the fuel filter (typically along the fuel line).
Use a socket set to loosen and remove the mounting bolts.
Disconnect the fuel lines from the filter, taking care to catch any residual fuel in a container.

5. Install the New Fuel Filter

Position the new fuel filter in place, ensuring the flow direction matches the arrow on the filter.
Reconnect the fuel lines securely and tighten the clamps.
Reattach the mounting bolts and tighten them to the manufacturer's torque specifications.

6. Reconnect Battery and Test

Reinstall the fuel pump fuse in the fuse box.
Reconnect the negative battery terminal and tighten securely.
Start the engine and check for any leaks around the new fuel filter.
