Guide :Air Tools & Compressors : 1 Hp, 4 Gal. Air Compressor
Air pressure gauge does not move on Craftsman 1Hp, 12 Gal. Air Co
I have a 12 Gal., 1 Hp, about a year old used very little. The pressure gauge does not move but when I take the plug out of the inlet to the tank it seems to be pumping air. I let it run for 15 min. and the gauge never moved.
