Bill, do you think the misunderstanding of the design was more
widespread. I think PL did not grasp it either. My recollection back then did
not include the center pipe but I could easily be wrong. I wrote Ed for
clarification. More importantly, I like the design and if my system proves
inadequate, I will build a version of yours. Seems like the outlet opening
around the tube where it enters the tailpipe might be restrictive.

Jerry, The size of the annullus is deceptive, you can size it to be very
low restriction. I finished the layout of the backward or inside out version.
