Coolant leak, again

Alright- since everything in my car seems to want to leak coolant- here's the latest piece:
The metal piece under the coolant temp sender (to gauge) where a hose to the water pump goes in- what the crap is that thing called? I'm guessing I need to replace it, since leakage is bad Thanks! Mark W.

Holy !! Batman No, well, here's the thing- the hose runs back to the water pump. The engine (block/heads) are out of a '96 F-150 (don't ask- it wudn't me! ), so I've had a few similar WTF moments. So I'm looking through the appropriate Haynes manual for the truck- no pictures that show it.
Okay- so from the front of the car, on the left bank (1->4), at the front right above the t-stat is where I'm talking about.
Sorry for no pics- no camera either Friends, beer, and sensitive electronics- bad things
Thanks again! Mark W.
