Would it be possible using a check valve at the tank and routing the exhaust line from the accuair manifold to vent the air back into the tank? Im not sure if the pressure from the exhaust side would be enough to open the check valve.
you answered your question
No it's not possible.
There is a way to feed a separate tank and have that feed the compressor, but its not worth it IMO.
Thanks for the reply guys. As I thought about it more I realized it would need to overcome the pressure in the tank. Adding another tank would be a waste.
