Hello all,

My reading of the forum and rules have cast a bit of doubt on the answer to this question. Are COTS venturi vacuum pumps allowed to be attached to the pneumatic system. R66 would seem to indicate no but the exceptions below perhaps indicate yes? Clearly vacuum pumps are ok when powered by legal motors, it is the venturi pump attached the pneumatic system I am hoping to clarify.

Thanks all
