the coat hanger went in 7 1/2" into the sender hole, does this indicate this plug is missing?
That plug is in there if it 7 1/2". 7 1/2" is right between the two horizontal oil passages in the block. Even if that plug was missing it would have no effect on oil pressure. The oil would by pass the filter if that plug was missing which would be bad but you'd have plenty of pressure.
