Stock fuel for now. Guy I seen use a hx40 from a 5.9 Cummings was hitting 15lbs of boost no problem. And as for the pedestal I know all about it I know my way around a 7.3 and 6.4 powerstroke quite well. But He feed and return for oil are on the bottom of the center cateidge and I'm just going to to tap the holes and put fittings In it.
