Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Replace Fuel Filter

Tools Required: Socket set, fuel line disconnect tool, torque wrench, clean rags.
Remove the fuel line connections from the fuel filter using the fuel line disconnect tool.
Use clean rags to catch any fuel that may spill during disconnection.
Unbolt the fuel filter from its mounting bracket using the socket set.
Install the new fuel filter in the same orientation as the old one, securing it with the mounting bolts to the specified torque.
Reconnect the fuel lines, ensuring they are seated properly.

3. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position without starting the engine to prime the fuel system.
Start the engine and check for leaks around the fuel filter connections.
Monitor engine operation for any roughness or stalling.
