what should the pressure of each side measure, not the differential pressure, but the gauge vaccuum pressure. Clymer's indicates 40mmHG or less to be in sync...but I want to know how much vaccuum I could expect if I just measured one side alone.

Sort of off the wall, but how many forum members remember vacuum windshield wipers??

That tells a lot about our ages. I drove several cars with vacuum wipers. I am also an old

***t.
