i hear about plenty of failures on 6.4's. But you are correct more of the failure's I have heard about are on cummins which do require more fuel pressure.

I've yet to hear of a FASS failure on a 6.4 and I've been personally running one for over 3 years issue free. Not to mention I've yet to get a warranty call for a FASS unit period since I've been in the diesel performance industry.

Not that I'm as familiar with FASS as some on here. But I completely agree with you. What failures do the 6.4 set ups see compared to other set ups.

the known disadvantages of the 6.4 lpfp:
doesnt filter debris or water well.
tab breaks off.
seal tears and pours out fuel all around the tab.
expensive annoying to replace filters.
allows hpfp damage from the aforementioned reasons.
no way in the world i would want to double the problems and have added cost in filters. if i could do it again id go with fuel lab. nevertheless rather have an AD over the factory lpfp.

The Air Dog that's on my old truck has well over 100,000 miles on it with no issues. I never had an issue and the new owner hasn't had an issue.

FWIW....If I wasn't trying something different and running a fuel lab 200gph Vortex pump...I'd be throwing a Fass on mine. Our local cummin's guy swears by fass and even on their Super Diesel and Super Street trucks they've had zero issues with theirs. I know the Super Diesel truck has a fass that has been passed around from multiple trucks. They're a local repair shop as well and have yet had a fass fail on them or make a warrenty claim via fass.
