Forgot to add my update.

It was the oil sender. Broke it off and finally found it.
I couldn't get a wrench around it, so I went to the auto parts store and bought a oil sender socket ($10 and made in the USA)
Removed the old one and installed the new one.. Connected the wire and the gauge reads oil pressure again. Another plus is I fixed the oil leak in the pump.

Now I am working on replacing all the fuel lines with hose, and I replaces the long brake line that runs to the back. I am better at flaring than I want to be.
