oil pressure

[gsbuick65]

ok i got my motor finished putting together, tried to prime up the oil system I can't get any pressure, the machine shop didn't pack the oil pump so I put oil thru the sending unit hole, still no pressure, do I need to pull the pump apart and pack it?

Put oil through the top oil cooler line at radiator.

Put the oil cooler adaptor on and dump oil through the lines.
