If your compressor is putting out 110 psi, but not getting air to tank, you must have an obstruction prior to the tank. I would suggest breaking fitting loose at tank & working backwards breaking each connection until you find blockage. This process should keep the blockage from breaking loose & ending up in tank or further downstream causing problems. Also, check to make sure flow is going through the check valve the same direction that the arrow points.
