With the engine off, is there anywhere I can hook a vaccum pump/gauge to and get a reading of any kind?

I hooked up to both hoses off the back of the tb and the hoses at the charcoal cannister and got nothing.

I plugged it into the hose at the cannister while it was running (engine speed changed when it was unplugged, so something is working) and got a fairly steady reading of about 16.

I'll be messing with it some more in the next few days, gotta head out to watch the superbowl for now.
