[DeTomaso] Vacuum source on IR manifolds

Hi, I am in process of installing IR fuel injection, using Fast Xfi 2.0.
Would like to hear from someone running similar setup how did you plumb vacuum source manifold.
Was planning to use just one common manifold (connected to all 8 runners) and then connect servo brake tube, MAP sensor and vacuum regulated fuel pressure regulator all to that manifold.
Would that work fine or will signal from MAP get wrong readings when breaking (booster maybe reducing vacuum)?
If this is fine, is there some rule on how to size this manifold?

Thanks, Robert
