When ignition is in run position how frequently and for how long does your vacuum motor run? If it stays quiet for 30 seconds or more I would say your vacuum lines are in good shape.
Also, I would have a couple of 3 way vacuum check valves handy just in case.
I would check all vacuum line plastic to rubber boot connections and if they are sliding relative to the other, I would slide the hard line out about a 1/4", dab of Crazy glue, slide back in. Also, seal the rubber boot shoulder with black silicone sealant followed by a zip-tie. 'Course all that is unnecessary on my car since I pulled the whole secondary vacuum off the motor now.
