I believe there is only the one vacuum/breather line from the pass side valve cover into the stock air hat... admittedly, I only have a 3.9, but I think the 5.9 is the same...

I have seen the nipple on the manifold, but no vac line on it... I think it's supposed to be capped...

certainly, I could be wrong so hopefully someone with a more definitive answer will post
