It should be simple enough to find out. Maybe I'll check it when I test all other control pressures. Just pull a vacuum on the port and see if we get an increase in control pressure as theorized.
BTW, I should soon have in my hands a Leaskified WUR...with the stronger diaphram (just some added assurance against future failure).
