A few ?? so i can finish up my 3rd gen swap! Options

[MGCustoms325]

Hi all,
Hopefully some of you that have completed your 3rd gen swaps will be able to help me ID a few things. If it makes a difference I am using a caldina IM on my 3rd gen 3S.

First, I need to ID what this hose goes to and what it does:



Where it is connected to the head



Next I need to ID this plug



And finally my mechanic wants to know what to use these for





And just to show my progress thus far:



Thanks!
