Before posting this question, I was searching at Summit... they actually have a selection to search out e85 vs alcohol... For e85 they show 2, for alcohol they show 20 electric pumps, which includes the ones listed for e85. There isn't a huge price difference between the majority of 125gph and 275gph models, and understand that this rating is at free flow, so it is only a guideline. There is a larger spread between 8AN, 10 AN, and 12 AN fittings. I am guessing that the 10 AN would be a good starting point , and the 12AN would give some room to grow? I don't mind spending a few extra bucks now, but don't see myself needing to support 1000hp anytime soon. I have no idea what a minimum requirement would be, so am open to suggestions.
Thanks,
Tom
