Installed this kit on my 2005 F350. I was sitting near OEM fuel pressure and when I installed this kit it jumped to 80 at idle and leveled off at around 70 after a week or two. I also discovered after opening the box that this was NOT the genuine Ford OEM part (which they later mentioned in the product description). Since they used the Ford part number in the main name, I ordered it thinking it was a Ford part. a misleading title which I'm sure was intentional which is why it only gets 4 stars.
