I have a 2006 F250 that I needed to fit a new ATK reman into. Well 1 month before the 3 year warranty it died, the oil pressure dropped. So I found a YouTuber called Ford Tech Makuloco who explained and showed that Ford OEM oil pumps are only required to pump out 12-25psi, which is not enough for this engine and its cam phaser problems. This beauty pumps over 60 at idle and over 70 on throttle. I expect my new second motor combined with this oil pump will give me what I wanted the first time. Note: ATK uses Dorman Cam phasers in their remainders. I had to open it up and replace them with $400+ OEM FORD phasers as Dormans ALWAYS fail. just so you know
