I’m with oldtimer. Buy the new sender and see what you need. And actually, on many of the oil pressure senders with plastic housings, breaking the top off gives access to the stem with is a common size hex. If you find a McParts store with a knowledgeable counterman you might get some quick answers and a loaner tool as someone suggested.
