what type of car? what engine management are you running? there are a handful of e85 stations. i have a few customers who only run e85. but on a side note, pending on your ems, some systems have the ability to run a flex fuel sensor. the MS3Pro that i use has this feature. you can tune a pump gas tune and an e85 tune and the ecu will merge the maps together pending on the percentage of gas it sees. Diyautotune makes the ms3pro and can probably answer more questions if needed, but if you want e85 and don't want to run into the issue of not finding a pump, this could be a great alternative.
