Oil pressure gage reads low
Hi, the oil gage on the cluster instrument panel reads low, too low.
However when I put a real gage in place of the sending unit into the side of the block it reads good-very-good, anybody else have this problem?

Could be that the tube to the gauge is clogged and not receiving the proper pressure to read accurately. I had a similar problem on an old 66 Pontiac Bonneville that I used to own.
The gauge itself is electric, but it plugs into a sensor and I would bet that sensor is connected to the oil pump by a small diameter tube to get the reading to feed to the gauge.
The oil pressure sending unit is just a little can that is screwed into a hollow extension from the block. It's located just infront of the oil filter. I was worried about my oil pressure once, so I replaced the sending unit, only to find that my wire had been corroding. I cleaned it off, and the guage shot up.
Amazing what a good connection can do!!!
