AIR GOVERNOR ADAPTER FITTING FOR M35A2, M809, AND SOME M54 MODELS. 

THIS FITTING IS USED TO ALLOW LINE FITTINGS OR TEE'S TO BE USED ON THE GOVERNOR. IF YOU HAVE AN M35 WITH THE ORIGINAL STYLE GOVERNOR THAT LOOKS DIFFERENT THAN THE UNITS WE SELL UNDER PART #'s 10900525-5 & 284358, YOU WILL NEED THIS ADAPTER TO COMPLETE YOUR INSTALLATION. 

LATER MODEL M35'S CAME WITH THE STYLE GOVERNORS WE SELL, AND THIS FITTING IS A FACTORY PART ON THOSE TRUCKS.
