I think it probably does act differently. By the way, nice video.

For one thing, the M103 is using CIS, not electronic injection. For another, the vacuum line goes to the breather hose between the valve cover and the air filter housing. As such, it doesn't get a signal that is representative of manifold pressure.

Ivanerrol said "I don't know if sucking on that tube would have been such a good idea."

I didn't suck very hard, just enough to see if there was a seal or not. There wasn't. It's not like I put a mityvac on it and sucked it down to nothing.

Upon examining it further, it seems like the rubber nipple is no longer sealing to the metal housing. It appears to pop in there much like a tire valve stem. I wonder if I can seal it up with some RTV or some other goop. Perhaps even rubber cement would work, or glue from a tire patch kit. At $400, it's worth a shot!
