    Default Stainless Braided Hose & Ethanol

    I've been using stainless braided hose, (stainless over rubber), for fuel lines for 40 plus years. I've used them for pump gas, race gas, and alcohol without any issues, until a week ago. I always drain my fuel, especially alcohol, to prevent it from attacking/eating uncoated aluminum and rubber. Last year while rigging a new boat I was told that all fuel hoses should be teflon lined as most fuels have ethanol added, which will attack rubber. Of course I didn't believe it, based on my years of experience, lol. Well last week while putting race gas in a boat that has always used race gas, I had a hose leak, badly! So I assume even race gas has ethanol?

    Can someone enlighten me on this? Thanks

    The newer braided stainless stuff doesn't even seem to last with pure racing gas that we run in a dirt modified car.

    That's because back then there was only good stuff. Same with fittings. Then the cheaper fittings and line started showing up and even Earls had to jump on board or get buried.
    Earls performoflex stands up to race fuel pretty well. It handles e85 pretty well.. Not so much with there Autoflex.
    XRP hose holds up well. I am sure that Aeroquip has some decent hose as well. But some of the cheaper synthetic rubber hose is not handling ethanol and some of the race fuels well at all.

    With gas draining the lines seem to make it worse. The line would dry out and get hard, but lasted longer if we left the gas in the line.
    Can't say with the E85, but I know people that aren't doing anything special except to pickle the engine when they done for the weekend. thing
