On my 1996 305 Vortec theres no oil psi sending unit above the oil filter , theres just a empty threaded hole , whats keeping the oil from coming out this hole and where is my oil psi sending unit ?

Is this it ?
I thought this in the picture was the oil psi switch like the TBI engines had! The one tied into the fuel pump!
I was looking for the oil psi sending unit , the one that feeds the oil psi guage in the cluster.
