Tools Required: Socket set, fuel line disconnect tool.
Sub-steps:
1. Locate the fuel filter, typically along the fuel line.
2. Use the fuel line disconnect tool to detach the fuel lines from the filter.
3. Replace the old fuel filter with a new one, ensuring proper orientation.
4. Reconnect the fuel lines securely and check for leaks.

3. Clean or Replace Fuel Injectors

Tools Required: Injector cleaning kit or replacement injectors.
Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the fuel injectors.
3. Remove the fuel rail to access the injectors.
4. Clean the injectors using a cleaning kit or replace them if they are clogged or damaged.
