Solution

1. Preparation

Tools Required:
- Socket set
- Fuel line disconnect tool
- Torque wrench
- Container for fuel spillage
- Safety glasses
- Gloves
Ensure the vehicle is on a flat surface and the engine is cool.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it to disable the fuel pump.
Start the engine and let it run until it stalls to relieve pressure in the fuel lines.
Turn off the ignition and disconnect the negative battery terminal to prevent any electrical shorts.

3. Access the Fuel Filter

Raise the vehicle using a jack and secure it with jack stands if necessary.
Locate the fuel filter, which is typically found along the fuel line under the vehicle.
If applicable, remove any protective covers or shields obstructing access to the fuel filter.

4. Remove the Old Fuel Filter

Use the fuel line disconnect tool to carefully detach the fuel lines from both ends of the fuel filter. Be prepared for some fuel spillage; use the container to catch any excess fuel.
Remove the mounting bolts or clips holding the fuel filter in place and take out the old fuel filter.

5. Install the New Fuel Filter

Ensure the new fuel filter is oriented correctly (check for arrows indicating fuel flow).
Position the new fuel filter in place and secure it with the mounting bolts or clips.
Reattach the fuel lines, ensuring they are fully seated and secure to prevent leaks.

6. Reassemble and Test

Reconnect the negative battery terminal.
Replace the fuel pump fuse in the fuse box.
Turn the ignition to the "ON" position (without starting the engine) for a few seconds to allow the fuel pump to prime the system.
Start the engine and check for any leaks around the fuel filter and lines.
