Message: [QUOTE="suprdzlduty, post: 1224309, member: 5805"] One thing to consider is that the Fass could be heating up, getting weak and dropping pressure, more importantly volume. The hpfp need volume over pressure...10lbs is what most lp systems are regulated at. Sounds like the dealer looked to see if it was getting air but I doubt the pump was hot when tested. Let's say the lp pump is good...now plumbing has to be the next part looked at. Isolating the pumps would be ideal, ie plumb it so one is feeding the injectors. Maybe you could post some pics of how the supply lines are run to the pumps to give us an idea what this kit looks like...if one pump feeds each bank, then one could be starving for fuel, which would cause aeration in that bank. The bolts missing and gap between the turbos is normal, unless it is leaking exhaust then it would need a new gasket, but still wouldn't need bolts and still be a gap. Back to the fuel tank...some of the early Fass pickup tubes caused 1/4 tank issues but I don't think they offered pickup tubes for the 6.4's but I could be wrong. I'm gonna assume you have plenty of fuel in it to eliminate an issue like this... [/QUOTE]
