Before you start
- Prevent the fuel from spilling while reinstalling the filter.
Procedure
- Loosen the fuel filter turning it counterclockwise with a filter wrench.
- With a rag wipe clean the fitting face on the upper cover so that the new fuel filter can be seated properly.
- Lightly oil the O-ring, then turn the filter assembly clockwise carefully until the O-ring is fitted against the sealing face of the filter cover.
- Turn 2/3 turn further with the filter wrench.
