You can get inexpensive vacuum check valves at an auto parts store. Best location on stone diffusers would be at the stone split. Old Chrysler brake boosters used a 3/8" inlet and outlet check valve available in all Dorman "Help" sections.
A better solution would be to upgrade to membrane disc diffusers which are self-sealing and provide FAR better performance.
