i found some more info on some foums, alcohol fuels(E85) are like brake fluid, they like to absorb water, they like to eat rubber too, need to use steel or stainless steel lines, no aluminum, E85 has a 105 octane rating, from what i've read its like running alcohol, bigger jets in the carb, maybe a guy could use a water/fuel seperator like diesels use to cure the water in fuel problems.
