Northern Maine isn't part of the N-RFG range. There seem to be 4 main blends of gasoline in the USA: standard, northeastern reformulated, southeastern reformulated, and California. N-RFG is year-round E10 blend with added oxidizer and no benzene. In the winter they dilute it with butane and that causes the boiling issue. I have an electric fuel pump and I have the line wrapped in spark plug wire heat insulation. I have been calling the gas companies in hopes of them committing to carrying at least one type of gas that does not exceed 10% ethanol. I remember looking at pure-gas years ago and discovering all the locations in MA sell in cans only.
I am trying to move north, though. I don't know if I'd make it farther than New Hampshire. As much as I like to pretend that becoming a woodsman is the ideal way to live out my days I sure like getting a paycheck every two weeks.
