engine is Cummins 903, turbo is (should be) ST-50. The brass nipple which is screwed into the bottom of the case is cracked and well, now totally separated. I put on this new turbo about 5 yrs ago. IIRC, I'd bet I reused some of the plumbing off the original turbo for the install.
any guesses if this will be a Cummins-only type part, which is probably NLA, or would this be a turbo mfg supplied part?
Without actually measuring, It appears to be 3/4 inch pipe, heavy wall, with NPT threads into the body, and a o'ring compression nut that attaches this nipple to a 90 degree elbow. overall length is about 3 inches. If all it is, is a o-ring compression, I might just find a piece of schedule 40 black pipe and cut it to fit. I'll see tomorrow what is involved on the other end of this nipple.
Engine was hot, so I just shut it down and walked away this evening.
I guess my biggest chore will be extracting the broke off portion out of the turbo body.. Yeah, it's flush.
