I wish I could tell you for sure, but I can say that one thing to be aware of is that E85 has a higher conductivity level than gasoline. Typically E85 cars have different fuel pumps than their strictly gasoline brethren. Since gasoline does not conduct electricity those fuel pumps sit submerged in the fuel with their positive, and negative leads fully exposed to the fuel. That's not something you'd be able to get away with where the fuel is more conductive.
