They make a barrier hose now for fuel that is supposed to resist the effects of the ethanol.
Have they changed the rules on marine engines and ethanol fuel? Probably okay if you don't have a fiber glass tank. Or was that what the problem was? Not a boater and don't remember just what was happening with them.
I know every year I get the joy of replacing the little primer buttons on our push mowers and weed eaters. I watch the rubber fuel lines on my air cooled VW like a hawk and change them regularly. Too many engine fires due to hoses breaking down.
I'm glad others aren't having the issues I've seen around here. Could be we really are getting bad gas while everyone else is doing okay.
I do know my VW Passat would average 32 mpg on unleaded regular fuel, but when I could no longer get that around here and had to buy the E-10, my mileage went to 26mpg. Not sure how that is an improvement. Others say their mpg hasn't dropped. So it has to be the blend we're getting rather than the ethanol content. Hmmm... something to ponder.
