The FASS system would work if you also had a fuel tank that is Ethanol resistant. On your boat and Dodge/Cummings, most likely all components downstream of the fuel tank is made to run on the modern respective fuel. I think everybody here knows that the rubber lines, fuel pump diaphragms and carburetor diaphragms (at least Carter) will dissolve if not upgraded to Ethanol tolerant. So after doing all this upgrade you have a superior system that is able to run Ethanol gasoline. It's the owner's choice. I choose to run non-ethanol so that I don't have to upgrade.
