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!
