Q: Connectors to Oil Pressure unit on 1992 Jeep Wrangler

The connectors (black) to the oil pressure switch has two sides. The side of the connector that attaches to the wiring (green) to the guage has a back plug that keeps popping out ( its white) and a little oil keeps leaking from it. I pushed it back in but it keeps popping out. Is it ruined - and can I fix it - or can I buy that little connector part and just rewire it to the guage wire ?

First you need to replace the leaking oil sending unit ASAP, before that fails completely and you lose all your oil and your engine!!
Thanks - I went ahead and did that - now the guage works again and so far the back of that connector has not come apart again. Perhaps I should wrap some tape around it for insurance ? Just so I understand - does oil actually try to blow out through that connector. Sorry if its a dumb question but I guess I don't quite understand how the oil sensor and its connections there work. Is the oil pushing agaist a piston and the wire measures the movement ? Anyway, mahalo nui loa for the reply - its greatly appreciated !
Oh, by the way - the part was $34.38 at NAPA - here in Hawaii -as was stated in another earlier post I read concerning oil sensors.
