ISC Turbo drain hose

We have a 2009 Damon, ISC 8.3 on Freightliner chassis. There is a tube (hose?), about 1" in diameter, that looks like it runs from the Turbo to the oil pan. It is covered in a coating of oil. Not really enough to drip, but it is oozing onto the oil pan and making it messy. I assume this should be replaced before we go on a cross-country trip. Does anybody know if it is just a generic piece of hose, or some kind of magic Cummins part?

The turbo oil drain hose would be special high temp oil resistant material ( no doubt have a Cummins P/N and price ), but I'd be tempted to clean it up , tighten the clamps and monitor , for any further seeping.

It is a Cummins part. If the leak continues after attempts to correct it, just buy and install a new one.
