Sorry, I re-read the OP was inquiring about something with E85...

I'd have a black Holley pump (alky compatible) and whatever regulator they recommend. The black pump will be as easy and cheap to rebuild as the blue pump, I would think. Spend the high dollar billet pump money elsewhere.

Where are you souring your E85 from?? Aren't you in the Sac area?? I think the closest station to me (Tracy) is Livermore.
