Don't forget to check the vacuum line going to the charcoal canister way forward in the LH fender. Don't know your year, but if its got an electric valve it should hold vacuum (MityVac test). My '89 n/a has short rubber hoses at each end of the hard plastic tube, each of those get little cracks.
Also, the hose & check valve to the brake vacuum booster (if you have one?) & its rubber grommet.
One way to test all dashboard vacuum hoses & stuff all at once. Each time you park the car, put the air distribution knob in a different position. After sitting for a few hours, you should still be able to operate the knob & have vacuum to work the dampers. Mine holds vacuum overnite. If your car passes this test, you don't have to inspect hoses under the dashboard. If it fails, it might just be the check valve on the reservoir rather than a 'real' leak.
