Why is oil coming out of these?

I was in panic mode. So, yes it is very possible it is the sending unit. When you watch it you'd swear it was coming from the plug though.
As soon as I got home yesterday, I plugged my oil sending unit off. Guess what. No more leak! The way the oil was hitting the little plug in the intake made it appear as if it was gushing oil out of there. I just wanted to be honest at the expense of my dignity and tell everyone they were right and I'm not too bright sometimes. Thanks to everyone who took the time to help me here!
