Hawk 250 vacuum line

Hey,

So I've got a brand new '24 hawk 250, and just installed the 28mm Nibbi carb and intake manifold. Unfortunately, I didn't notice until after the install, the new replacement nibbi manifold does not have a vacuum port on it like the original intake manifold does. The original manifold has a vacuum line running to what looks like some kind of valve (maybe the PCV system?). It has two larger hoses connecting to it. One leads to the air box, the other leads to the engine head. What do I need to do to finish this job? Can I just leave this vacuum line unconnected to anything, or could that cause issues?
