[QUOTE="6.0 Tech, post: 1560753, member: 23001"] Verify your primary fuel filter is fully tight. Also seen a bunch where o rings have worn out on some of the quick connects, not enough to leak externally, but enough to suck air. Maybe disconnect them and put some dielectric grease or trans gel on the orings and see if pressure comes up some. Also, the 11-14s were fairly common for the fuel pressure switch to leak, and contaminate the pigtail, kinda like early icp sensors on 6.0s. Verify that is also not a problem. Another thing, since you haven’t owned it it’s whole life, it could be a partially restricted sender from an additive cap or maybe some other shit that may be in the tank.
