I've had this compressor for awhile. I recently replaced the oil pressure gauge and changed the oil per tech data. I started up the compressor and there's no oil pressure reading on the gauge but the compressor will make 4500psi with no problem. I previously removed the oil pressure gauge to check for oil flow and there is oil flowing but 0 pressure on the gauge. Any Idea what could be wrong can't seem to find any information on this...
