hey guys. on my 12v cummins the turbo drain tube that goes into the block is their a o-ring or is it a press fit?? the guys over at cummins don't even know?? the picture they have dose not give them a part# but the install diagram shows 2 o-rings?? anyone who has information is awesome.

 

Well, the part shows being push in, but they also show an o-ring, but the parts book says not required.

I would get one anyway and have it on hand, see breakdown below.





If you need anything else, let us know.

 

I've seen both O-ringed as well as press fit.
