I have a buddy that has a Fass on his 2006 Powerstroke and he is wanting to go bigger. My question is he is willing to buy a bigger Fass for a d-max and sell me his old pump with all the new brackets, plumbing, and wiring. Will his old pump work on my truck sense they are running way higher fuel pressure than what we can run? Are all the pumps adjustable on fuel pressure? Thanks in advance!
