Did the vehicle ever have a power adder? You do typically see some sort of check valve on the vacuum modulator when a blower or supercharger is used.
Other than that I couldn't really think of a reason to have that type of orifice on the line.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
