I took apart my oil pressure gauge awhile back for general clean-up, along with all the other gauges. I figured that I should check the accuracy of the gauge. I started up the air compressor and had the gauge rigged up to it through my air blower. Solid connection...no possibility of leaks. As the pressure built up, I noticed that the readings on the oil pressure gauge are lower then that of the compressor gauge, which I know is fairly accurate. At 60 psi on the compressor, I'm showing about 45 psi on the OP gauge. Can this be adjusted and what is the procedure??
