Engine/Transmission (1994 - 1998) Turbo oil feed line O-ring

[Got Smoke?]

Anybody have any idea what size this O-ring is? Mine was leaking on my last turbo swap, and I'm doing another Tuesday.



A cummins part # won't help me because I don't have time to run all the way to Nashville for an O-ring. If anybody has a good idea what size it is I can probably get one at a parts house.



Thanks in advance!
