Dumb vacuum pump question... The standard crankcase vent system sends the vent to the intake manifold. On a car with a vacuum pump would it be a good idea to vent it back to the intake?

No... bad idea. You will get alot of oil mixed with the vacuum pump blade material. You don't want any of that garbage going back in the intake. Just leave a breather on the catch can.
