I took the truck back to where I had it serviced. They were willing to look at it free of charge since it was just in. The same tech that did the work looked it over - young guy admittedly not a diesel tech. He was good to work with, though. I was with him in the shop looking it over - sure enough the seal was twisted and deformed. I treated the tech very well and we got along great. He admitted the screw up. I got a new seal installed - properly - and we bled the fuel system. There was a LOT of air in the low pressure side. It was just gurgling when we charged the system - no bueno. Once we had nice flow we put the lines back on and buttoned it up. The noise I heard was immediately gone. Easy fix. I don't think the tech will forget how to install a fuel filter on a 6.7 now. We had fun doing it, but the extra work still could have been prevented.

Crap happens. Accepting it and being a good sport over it goes a long way. I think the whole service department got a good vibe about the work. I just hope they didn't blast the tech over it after I left.

I had the service writer note the air entrainment in the fuel system. Whether or not it is warranted - my concern is the high pressure fuel pump. If there is air in the supply to the high pressure side that may be an issue. If the high pressure pump goes soon it is all documented in OASIS that the fuel system had air in it.
