[QUOTE="Spoolin', post: 732864, member: 11060"] Fuel pressure was at 50 psi idle and would drop to 40 with just half throttle. I immediately bought and installed the updated "blue spring" and it brought it up to about 60 psi at idle. At half throttle it drops to 50psi which is a lot better than before, however at WOT it still plummits. Usually goes down to 25psi, however I have seen as low as 15psi. I also installed the 6.4 banjo bolts and it made no noticeable difference. A lift pump is next on the list. [/QUOTE]
