Hello. I have a vacuum gauge installed in my car, it has an M47. It ranges from about 17 when engine braking and 0 when accelerating. Is that a normal range?

Secondly, my vents switch to the footwell when I accelerate. I have the A/C on on recirculate. Also there is a hissing sound. Where is there a common leak? Could the vent Vacuum cause the gauge to ho to zero?
