First and foremost, why would you want too? Ethanol makes less power than gasoline and is only slightly cheaper. You actually have to buy more ethanol (almost 2 gallons) in order just to get nearly the same efficiency as one gallon of gasoline.
Please don't tell me you are trying to improve gas mileage or get a tank of gas for slightly less...
Plus why mess with a new cars fuel system?
