91 f-150 massive oil leak

I have a 1991 ford f-150 4x4 that has had an oil leak for quite some time and it had gotten progressively worse. As the engine heats up, the oil begins to literally pour out. The oil is definatley coming out of whatever is in between the firewall and the engine itself. Can feel where the oil is coming from by putting hand behind engine, but can't see whats going on back there. The leak is definalty located high up and takes a fair bit of time to reach the ground. I have looked through many engine books and cannot identify exactly what is back there...maybe some kind of booster oil pump or something to do with environmental controls?

Not sure if this is where it's located on that vehicle, but it may be the oil pressure sending unit.
