Question About Craftsman Air Compressor 921.166390
Air compressor 921.166390...

Pressure only builds to 30lbs then stays there. Air compressor keeps running. Tightened all connections. Haven't found any air leaks. Does not hold 30lbs after being shut off, and i can't find any air leaking after shut off.
