AN fittings for E85
Aluminum and zinc would probably take several years to degrade with ethanol (compared to months with brass or rubber), so it's technically safe for a little while. I'd avoid it and stick with steel fittings, though.
The thing that can get you in trouble is storing it for long periods of time because it's susceptible to moisture which is what is bad. .. I drain my car every fall and put pump gas in the system .
Corn alcohol ftw!
