Solution

1. Preparation

Tools Required: Safety glasses, gloves, socket set, fuel line disconnect tool, torque wrench, OBD-II scanner, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Fuel System

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Turn off the ignition and disconnect the battery.

3. Remove the Clogged Fuel Filter

Sub-steps:
1. Locate the fuel filter (usually along the fuel line under the vehicle).
2. Using the fuel line disconnect tool, carefully disconnect the fuel lines from the filter. Have a rag ready to catch any spilled fuel.
3. Remove the mounting bolts or clamps securing the filter using a socket set.

4. Install New Fuel Filter

Sub-steps:
1. Position the new fuel filter in place and secure it with mounting bolts or clamps.
2. Reconnect the fuel lines, ensuring they are seated properly to avoid leaks.
3. Tighten the connections with a torque wrench to manufacturer specifications (typically around 15-20 Nm, but verify with a service manual).

5. Refill and Test System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Turn the ignition to the "ON" position (without starting the engine) for a few seconds to prime the fuel system.
3. Start the engine and check for leaks around the fuel filter and connections.

6. Clear Codes (if applicable)

If any codes were stored, use the OBD-II scanner to clear them after confirming the repair.
