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.

And eventually they added a vacuum pump to the fuel pump to give a little
extra suck when going up hill. Electrics fixed all that crap.

I had a 39 Chevy Master 85, when you hit the brakes the wiper would
slow. The harder you hit them the slower they got. When hitting the gas
they would start racing bepending on how much you gave them. It didn't
seem to matter is one was going up hill or not as far as I recall. But
then I got rid of the car in the mid 90's and had not driven it for a
while before that.

Vacuum wipers, you gotta love em!

Some of the fords and Merc, I've had, the air vents worked on Vac.
also.
In the hot summer, if you accelerated, the vents would close and the
conditioned air would shut down. let off the foot feed and it would
freeze you out. Same way with the heater....
