Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety while working on the fuel system.
Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Access the Fuel Filter

Locate the fuel filter, typically found along the fuel line, under the vehicle.
Use a jack and jack stands to lift the vehicle safely if necessary.

3. Remove the Old Fuel Filter

Place a catch pan underneath the filter to catch any spilled fuel.
Disconnect the fuel lines from the filter, using a fuel line disconnect tool if required.
Remove the mounting bolts or clips securing the filter and take out the old fuel filter.

4. Install the New Fuel Filter

Ensure the new fuel filter is oriented correctly according to the flow direction marked on the filter.
Secure the new filter in place using the mounting bolts or clips.
Reconnect the fuel lines, ensuring they click securely into place.

5. Test the System

Reinstall the fuel pump fuse and reconnect the negative battery terminal.
Turn the ignition to the "ON" position (without starting) to prime the fuel system and check for leaks.
Start the engine and allow it to idle, monitoring for any abnormalities.
