Zetec help

[Shorty]

1. Is brake servo, just needs blocked
3. Looks like the other end should push straight onto the fuel pressure regulator
I wasn't sure about 2. What is the fuel vapour recirc system actually for?

I'm also planning on using a zetec on standard inlet and look exactly the same. I'm guessing from a focus as I think the mondeo inlet is slightly different.
