OK.
First set the well pump switch on the 12v pump 50 to 70 psig, then the well pump switch on the 120v compressor 70 tto 90. That way they won’t try to cross talk one another if both are on. The engine compressor should kick in at 90 and out at 125.
The potties and doors which are fed by the low pressure circuit use lower pressure, that is the purpose of the regulator.
The purpose of the check valve located on the TEE going into that small tank is to prevent the 12V compressor from trying to pressurize the entire air system. When you replace it pay close attention to the direction on the valve. The 120V and engine compressor feed the low pressure section of the air system but the 12v does not feed the general system.
The buzz is the check valve. The leaking regulator is either a bad regulator OR someone installed it backwards. Backwards meaning the inlet and outlet are reversed.
