With those oversize pumps you also need to inspect them for proper outside diameter. If it slips in easy it is probably no good. I have come across a few that were about .005" too small. If not a tight fit they can leak at both the inlet and outlet both of which will reduce oil pressure. Send the defective one back.

Yeah, I just installed the oversize pump to prolong the inevitable engine replacement.
