1981 280zx vacuum lines

Hey everyone, thank you in advance for your help!

I bought my first z, 1981 280zx, and trying to get it dialed in and put together right. seems most my vacuum lines are in order although there are a few small discrpincies from the kind of vauge diagram under the hood. Below is one particular line im not certain of. Any help would be greatly appreciated.
