No pump, vacuum from the intake manifold is the source.
When did ford start pulling a vac, from the intake manifold? AFAIK,
they've always used a pump

Maybe you are thinking of the "air" pump that was installed in all cars
to inject clean air into the exhaust to "improve" emission readings.

Engine vacuum has been used for years for power brakes and on older
car's features like flip-up headlights and even the windshield wipers
(on really old cars).

Didn't you just love it when you stepped on the accelerator and wipers
slowed or stopped?

Only when going uphill, if memory serves.

Up hill was the worst case scenario but even flat land heavy acceleration
was a problem. It did seem to vary somewhat depending on the car brand.




Most of my cars in those days were either grossly underpowered or Jeeps,
which I believe had electric motors attached to the windshield and which
drove the wipers.
