Click on the attachment for the instructions for removal of the valve block. There is a diagram of the air line placement that will help you. I've also included instructions for the replacement of the air compressor.

Hello, at the tip of the fob should be a red lens, if you press and hold the button on the fob a few seconds the red light should flash indicating the battery is ok., can you try this?
