    We bypassed the dryer and have air to the tanks but after that no air in the tanks don't know what is going on. Was letting air build up went in the office and heard a loud bang like a gun shot. Can't figure this out!!!!!!

    The last time we had an air leak one of the air bags was bad check your air bags while the truck is running to see if you are leaking air while the compressor is trying to build air pressure Use a spray bottle with soap & water to detect the air bubbles.If your compressor does not build air at all then you may need some help from a truck dealer.Call mack service dept. and see what they say about it.
