If you are having vacuum problems, don't forget the fuel filler and trunk locks.
I bought a "Siverstone" hand vacuum pump out of an ad in Autoweek magazine about 10 years ago and it has served me well ever since. It came with an assortment of of plugs and adapters and cost about $30. Oiling the cylinder once a year has kept it as good as new.
Tne nice thing about vacuum is that you cannot spill it, shock yourself, our burn yourself. It will not explode.
