ISM500 sending unit leaking

With the rear engine access door open and looking at the engine block, there is a sending unit of some sort that is approximately at 12 0'clock and a foot above the bottom pulley. There is a wiring harness in a loom that runs to the unit and then continues. At a quick glance, there is a large connector which attaches to this unit. There is a slow oil leak which is slowly making a mess.

Could not find anything on the Cummins site.

Any ideas out there?

It sounds like the oil feed line to the turbo.
