Yes. That is your manifold vacuum port on the intake manifold. It is there for exactly that purpose. It's where the factory plumbed their vacuum from for the same functions.

I think you will need to add a vacuum check valve if there isn't one already on your booster.

Vacuum sources can be either ascending or descending , meaning that as rpm rises vacuum rises ( carburator ) or drops off ( manifold ) . I don't know what your trans is designed for . But 52 merc has said this is the proper placement so you should be fine .

Ford transmissions used full manifold vacuum to a modulator at the transmission. The Factory tee off the intake would have looked something like this. The large port for the brake booster, small port for the transmission.

Sounds like the reaction valve in the booster is defective or the boot on the rear of the booster isn't open to atmosphere.
