Where to find part # to this hose?

[SquareOne]

Not so much a Freightliner part question, but most likely something many of the Cummins ISX15's share.

I'm trying to find a small rubber hose (coolant) that is located on the very back, lower corner of the EGR cooler. The hose makes a 90degree bend and is very short. Maybe 3/4" in diameter. Looks like the hose connects to a pipe thread fitting that is screwed into the cooler housing.

Quickserve doesn't show it on their diagram. I'll get a pic when the weather lets up.

When doing an inspection this morning, I noticed the damn thing just starting to seep on the cooler side, so I want to go ahead and replace it.

Thanks in advance...
