Solution

1. Preparation

Tools Required:
- Socket set
- Screwdrivers (flathead and Phillips)
- Pliers
- Fuel line disconnect tool
- Safety glasses
- Gloves
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative terminal from the battery to prevent any electrical issues.
Relieve 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 under the vehicle, typically situated along the fuel line near the fuel tank or engine.
If necessary, remove any protective covers or shields using the appropriate socket size.

3. Remove the Old Fuel Filter

Use the fuel line disconnect tool to disconnect the fuel lines from the filter, taking care to catch any spilled fuel in a container.
Remove any mounting bolts holding the fuel filter in place using the socket set.
Carefully extract the old fuel filter from its mounting bracket.

4. Install the New Fuel Filter

Position the new fuel filter in the same orientation as the old one and secure it to the mounting bracket with bolts, tightening to manufacturer specifications (typically around 7-9 ft-lbs).
Reconnect the fuel lines, ensuring they are properly seated and secured to avoid leaks.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Reinsert the fuel pump fuse and turn the ignition to the "ON" position for a few seconds to prime the fuel system.
Start the engine and check for any leaks around the fuel filter and connections.
