Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the vehicle's battery to prevent any electrical issues.

2. Remove Fuel Filter

Locate the fuel filter (usually found along the fuel line under the vehicle).
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter. Use a line disconnect tool if necessary.
Remove any mounting hardware securing the fuel filter in place.
Carefully remove the fuel filter from its bracket.

3. Inspect and Replace

Check the old fuel filter for any visible damage or excessive dirt.
Install the new fuel filter, ensuring it is oriented correctly according to the flow direction marked on the filter.
Reattach the fuel lines, ensuring a secure fit to prevent leaks.
Reinstall any mounting hardware.

4. Reconnect Battery and Test

Reconnect the vehicle's battery.
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 for a few minutes, watching for any irregularities.
