Mods are in sig. Torque converter just let go in my tranny and my injectors have been struggling all winter. I just picked up a stock low mile tranny. I was planning on throwing a suncoast converter and input shaft in it. Next thing i was thinking about doing is running Warren Diesels 190cc injectors. My question, obviously im going to have to run a lift pump. What GPH pump will supply enough fuel to 190's? The big question do i HAVE to run regulated return? Any other input/suggestions/brands would be appreciated!!
