Help identifying fuel leak.

Howdy folks,
Got me a problem I need some help with. I'm working on my 1995 F350 xlt with the 7.3 turbo diesel. I have a fuel leak coming from a sensor looking thing on the back of the fuel bowl just above the mechanical fuel pump. I can't seem to find anything saying what that piece is so I can't find a replacement part. What is that part called?
It looks like a vaccum line or small spark plug going into the fuel bowl directly above the mechanical fuel pump. It's leaking just aft of the bowl. Anyone got a diagram of the back of the bowl? Or know what I'm talking about?

EDIT:
I may have figured it out. Would this happen to be the fuel filter restriction sensor?

You probably are right on the fuel filter restriction sensor. They are known to leak.

Correct, fuel restriction sensor. It is 1/8"NPT thread. I replaced my sensor with a brass plug, works fine.
Was surprised out how much of a drip can come out of that sensor.
