'68 C10 LS1 with oil leak

I've got an oil leak at the rear of the engine behind carb. It appears to be coming out of an oil sensor? I know I've got an oil sending unit just above oil filter so I'm not sure. Also if I remember correctly it used to have a T type shape like the 3rd picture I'm attaching but now it doesn't. Did I lose something?

Yes that is a oil pressure sending unit, and it will leak plugged in or not. If you have another one that your using for the guage you can just cap this port off with a plug.
