I wasn't planning on trying e85 but I thought if I could do it with the injectors I would give it a try. I got a deal on them locally used with a matching chip and regulator.
You would need double pumps most like or a single at higher voltage and or replace the feed line. Keep in mind the head pressure will be higher with stock lines. May need 80+ at the head to get 75 at the rail. Pump output typically drops off drastically as pressure is increased. Adding voltage seems to offset the problem a lot.
