NO vacuum.. my first real problem

Hi folks,
my car is still sitting on a lift and it is getting better by the hour... all things are almost done

since my fuel pressure/vacuum gauge came in today I decided to do a little test run tonight. I had some suspicion of a faulty vacuum system, since the car cam from AZ and quite a few rubber parts are hardened and shrunk over the years alowing for air leaks....
well anyhow... I connected the vacuum gauge with a t adapter on the ingnition advance vaccum hose... startet the car and..... ZIP ZILCH ZERO NADA.. did not even move that sucker :eek:

where do you suggest do I start to test for the fault?

Thanks a LOT!!! Mike
