Oil pressure guage pegged at 60

[AZDesertDog]

I have a 1984 Chevy K5 Blazer with a carbed 350 in it and the oil pressure guage is pegged at 60. I disconnected the sensor itself which is located by the oil filter if I'm correctly informed and the guage itself still moves a bit. So I have a question: When I unplug the sensor itself should the guage drop back to the left or peg itself at 6 still? And what could cause it to constantly stay at 60?

sending unit is bad.

Every oil pressure sender i've seen is located behind the intake manifold just to the drivers side of the distributor.

Do a search of my posts and you will find a GM 90 ohm gauge diagnosis guide. On my 87, the oil pressure sending unit is next to the filter.

Yeah pretty sure mine is next to the filter. I'll try replacing and see what that does.
