Looking closer it looks like it is just zip tied next to it.

Here is one from a cat 30 and you can se a hose attached going down some ware. Maybe just to the bilge.

The second photo shows the correct manufactured installation. The first one is not correct, and would pull a vacuum on the crankcase and draw oil up through the filter and into the intake in a way that it was not designed to do. Remember, this is a diesel engine, and the intake setup is very different.
