i would guess the vacuum readings would be the exact same as you would get at any of the vacuum ports on the engine.

The regulator has what appears to be a vacuum line. This is NOT a vacuum line, nor should it be hooked to a vacuum source. It simply collects vapors from a failing regulator for emission purposes.

Edit: provided we are talking about specifically about TBI engines

Well... the tube doesn't just end in mid-air. What ~does~ it connect to? If it's collecting vapors from a failing regulator, where does it take them? What is on the other end of the line?
