Using Cliff?s procedure post #121, my leak was confirmed to be check valve, but I have not changed it yet.

Did you try Jerry?s Gaskets? You?ll easily be able to test the actuators pulling the plenum. Not sure where else to source new other than EBay when they pop up. Sorry, I have some extra NOS, but don?t have access to them now. Be sure to check new ones because of the diaphragm incorrectly built from factory. I had to refund and replace two when I found them new.

Some people will tell you to remove the secondaries, but that is not an option for me. I also like them to work as designed.
