Hello, I have a 1988 f250 7.3 idi 4wd. She keeps losing prime so I'm killing my batteries and starter trying to re prime. I want to delete the mechanical pump and put a facet pump in to replace it but I've noticed there's a lot of vacuum lines coming off of the fuel pump. Looks like its for the brake assist and the a/c heater and what not. Is there a way to bypass this or can I just put an auxiliary pump in just to prime it and keep the mechanical pump?
