REMOVAL

1. Allow the engine to cool down.
NOTE: Mercury MerCruiser recommends that the engine be shut off for 12 hours prior to
filter removal.
2. Close fuel supply valve, if equipped.
Dispose of fuel‑soaked rags, paper, etc., in an appropriate air tight, fire retardant
container. Fuel‑soaked items may spontaneously ignite and result in a fire hazard which
could cause serious bodily injury or death.
3. Wrap the water‑separating fuel filter with a cloth to help catch any fuel spills or spray.
4. Remove and discard the water‑separating fuel filter and sealing ring from the mounting
bracket.

INSTALLATION

1. Coat the sealing ring on the new filter with engine oil.
Tube Ref No.
2. Thread filter onto the mounting bracket and tighten securely by hand. Do not use a filter
wrench.
3. Open fuel supply valve, if equipped.
4. Ensure that engine compartment is properly ventilated.
Overheating from insufficient cooling water will cause engine and drive system damage.
Ensure that there is sufficient water always available at water inlet holes during operation.
5. Supply cooling water to the engine.
6. Start the engine. Check for gasoline leaks around the fuel filter assembly. If leaks exist,
stop the engine immediately. Recheck the filter installation, wipe up any spilled fuel,
and properly ventilate the engine compartment. If leaks continue, stop engine
immediately and contact your authorized Mercury MerCruiser dealer.
