So far I have moved an adjustable fuel regulator up to the front and ran -6an (3/8") fuel supply/return lines. I also have a modded rail with a larger inlet fitting welded on it. Slightly larger e55 injectors also. Now I'm seeing many affordable flex fuel kits available, trying to figure out a strategy for that.

Edit: just saw I'm repeating info, lol. I'm working out a few bugs ( wandering pressure) before moving along.
