Default 79 oil pressure sending unit

I've tried several different sending units and they all seem to be junk to me. The current one just stays pegged 99% of the time. Every once in a while it will actually read. Has anyone found a specific one that seems to work like it's supposed to?

chances are wire , gauge, or cluster backing issue.
new senders work normal but the true pressure is off a touch

There's been more than one thread on this just in the last year. Everyone is having issues with replacement oil pressure sending units.
Myself included. The one I have in now I purchased from Zip. But it came in a NAPA box. It reads about 20 lbs high. But reads. I tried a standard motor products sender, it seemed to work perfectly, for about a month. I forget the third, it was junk from day one.
Really a roll of the dice to get a good one.
If you find one, and there is actually more than one.
Let us all know!
