Are the problems being caused by the fuel containing ethanol itself or water contaminating the fuel when attracted by the ethanol? If the latter would an additional water separating filter between the tank and engine help solve the problem?

Both. Additional water separating capability is always nice, but the ethanol is attacking the resins in some older fiberglass tanks.

The ethanol can absorb a lot of water. Your car's sealed fuel system keeps out moisture-laden air. Your marine tank is vented to the atmosphere, and the vent is right next to the water. The ethanol is hygroscopic, it sucks moisture out of the air, and when it gets enough, it "phase separates" and the moisure combines with the fuel to make an orange colored snot. That's what gets into the carburetor and fouls it. > If the latter > would an additional water separating filter between the tank and engine help > solve the problem? > Yes, it will. It must be 10 micron, Defender has a Racor that's just the right size for an outboard. I installed one over a month ago, and have been using the PRI-G stabilizer- no more problems. Steve Sipe
