I've been chasing Vapor Loc on my boat for a number of years. It is now under control to a tolerable level but still annoys me no end. Finally today a light bulb goes off in my head. (Not the boats!). Why not lower the operating Temp. from 170 to 160 or lower? I welcome all comments with Thanks! Al W. BTW, Boat is used here in New York, and the gas is 10%+Ethanol.
