Off a vacuum pump.

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?
