Booster line looks fine. Vacuum tested branch lines, booster holds vacuum, cannot find an excuse for loss of vacuum other than the pump itself. Have to rebuild. Also had to leave it there, I had everything I needed but the correct length 3/8 extension.
Since I wasn't there, and my daughter's description leaves much to be desired, I can't risk starting the car until I get the pump off and have a look and either rebuild the pump or toss it.
Take it from one with experience- it must be better to go ahead and repair the pump at home with the car in the garage rather than 27 miles away!!! Repair those pumps!

-sigh-
