#8 is a feed from the vacuum pump, it is merely Tee'd into the vacuum supply to the VCV. It is not a VCV signal. Regardless of what the VCV is doing, #8 should ALWAYS have system vacuum present. ...

#2 will never be greater than 12-14" of vacuum. It is a "controlled" vacuum leak. #1 should have full system vacuum as well as #8. #2, #3, #5, and #6 should all be at VCV vacuum level.

It's...

The BFS is a vacuum amplifier. It sums the inputs from the VCV and PRE inputs to give a modulated vacuum signal out on the TRA output.

Your vacuum input from the VCV is spot on.
