Could anyone clarify what the following vacuum lines are routed to?

33735

I am having a huge brain fart and figure two run to the charcoal canister, one must go to the fuel pressure regulator, so that leaves one...

Can anyone confirm what these go to that is using this style manifold?

The bigger of the 4 will go to the pcv on the intake side of your valve cover the other three are the vacuum ports that go to the fpr,WG,BOV.
