E85 required more volume of fuel than comparable gasoline.
You will have to throw away all your rubber lines and you will need a new fuel filter and (probably need to get a couple) as the E85 is going to clean out anything currently in the system. You will also need a alcohol compatible pump, and depending on the carbe you will have to completely rebuild it removing any rubber parts that the fuel will encounter, OR buy a specific E85 Carb if you are looking for the most out of this fuel.
Here is an article on converting to E85:

Why are you at 13:1?

People are finding out that the 105 octane rating is a little high. The real number seems to becoming closer to 94-98. At 13 to 1 you might be too high for e85.
