Solution

1. Preparation

Gather tools and parts: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, replacement fuel filter, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface, and the engine is cool.

2. Disconnect Battery

Disconnect the negative terminal of the battery to prevent electrical shock or short circuits.
Safety Warning: Always disconnect the battery before working on the fuel system.

3. Relieve Fuel Pressure

Locate the fuel pump fuse and remove it.
Start the engine and let it run until it stalls; this will relieve any residual fuel pressure in the system.
Turn off the ignition.

4. Remove Old Fuel Filter

Locate the fuel filter (usually located along the fuel line under the vehicle).
Use a socket set to remove any mounting bolts or clips holding the filter in place.
Carefully disconnect the fuel lines from the filter, using a rag to catch any spilled fuel.
Remove the old fuel filter from its mounting.

5. Install New Fuel Filter

Position the new fuel filter in place, ensuring the flow direction matches the original installation (usually marked on the filter).
Reconnect the fuel lines securely to the new filter.
Reattach any mounting bolts or clips, tightening them to manufacturer specifications (refer to the service manual for torque settings).

6. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Reinstall the fuel pump fuse.
Start the engine and check for leaks around the fuel filter and connections.
Allow the engine to run and monitor for proper operation.
