Draining Water from the Cool Fuel Module

Mercury MerCruiser recommends draining the Gen 3 Cool Fuel Module if it is equipped with a drain plug.
1. Remove the drain plug from the Gen 3 Cool Fuel Module and allow the water to completely drain from the module.
2. Inspect the drain plug and the O‑ring for damage. Replace if needed.
3. Place the O‑ring on the drain plug and apply Perfect Seal to the threads. Install the drain plug in the module drain hole.
Tighten the drain plug to finger‑tight.
