Look for a vacuum line between the throttle plate and intake. This is port vacuum. Pretty much any 3/16" or 1/4" vacuum line will do.
At idle you should read a little over 17" hg. on the gauge. If the gauge reads and stays steady no needle jumping your internal engine is good i.e. valve guides valve seals and seats are good if the needle jumps around then I would suspect one of these.
As you open the throttle body to rev the engine your vacuum will drop and when you close the throttle plate you should see a spike in vacuum then settle back to around 17hg.
Step on your break and watch the gauge if the vacuum drops you could have a bad cruise control vacuum switch, a bad break booster or brake booster check valve.
