4. Disconnect the fuel lines by releasing the clips or pressing the tabs and removing the hoses.
5. Disconnect the electrical connector if applicable.
6. Use a flare nut wrench to loosen and remove the fuel filter from the fuel line.
7. Apply a light coat of petroleum jelly to the O-rings of the new fuel filter.
8. Tighten the fuel lines securely by hand.
9. Plug in the electrical connector if applicable.
10. Start the engine and let it run for a few minutes. Inspect for leaks.
