Default A/C vacuum problems Help

Hey guys, here’s the story and I hope someone can help.
I replaced my intake with an LS6 intake and while doing so we broke the little vaccum line behind the manifold. I ran a new fuel/vaccum line directly from the canister in the passenger fender well to the intake and buttoned it up. The problem is that the AC is blowing out of the proper vents but it is NOT as powerful as it used to be and very weak. I can’t figure out what the problem could be? Did I use wrong vacuum line?( It’s 3/16)
Definitely a real head scratcher and I could really use some help on this if anyone is familiar. 🤷🏻‍♂️🤷🏻‍♂️
