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 the fuel supply valve, if equipped.
3. Disconnect the Cool Fuel Module harness from the engine wiring harness.
4. Turn the key switch to the start position and allow the starter to operate
for five seconds.
5. Turn the key switch to the off position.
6. Loosen each filter assembly retaining screw until the screw is disengaged
from the Cool Fuel Module. Do not remove the filter assembly retaining
screws from the filter cap.
7. Unseat the filter assembly by grasping the filter assembly handle and
pulling upward. Do not remove the filter assembly from the Cool Fuel
Module at this time.
8. Allow any fuel that may be in the filter assembly to drain out through the
bottom of the filter assembly and into the Cool Fuel Module filter reservoir.
9. Remove the filter cup from the filter cap by grasping the filter cap and
rotating it in a clockwise direction while holding the filter cup stationary.
10. Remove the used water‑separating fuel filter element from the filter cup,
place it in a clean, approved container.
11. Dispose of any water or debris that may be in the filter cup.
Installation
1. Install a new water‑separating fuel filter element into the filter cup. Push
the element into the cup until completely seated.
2. Install a new O‑ring on the filter cup.
3. Attach the filter cap to the filter cup by grasping the filter cap and rotating
it in a counterclockwise direction while holding the filter cup stationary,
until the filter cap locks securely into place.
4. Install the fuel filter assembly slowly into the Cool Fuel Module to prevent
spilling fuel, and align the screws retained in the filter cap with the screw
holes in the Cool Fuel Module. Tighten the filter assembly retaining
screws until hand‑tight.
5. Ensure that the filter cap is firmly seated against the Cool Fuel Module
and torque each filter assembly retaining screw.
