Generation IV External Engine - What are these hoses that came with my LS3 intake?

I bought an LS3 intake off of a 400 mile 2010 SS Camaro. The seller threw in a couple hoses, and I want verification of what they are & how they install. It's unlikely that I'll actually use them, but it'll still be good knowledge.

Here's the pic:

The bottom hose is a fuel line, but I'm not sure how it attaches to the inlet on the fuel rail. Granted I didn't spend much time experimenting...

The middle hose appears to be the line that attaches at the back of the intake and goes to the brake booster.

Not sure what the top one is. It's not the line that attaches to the front of the intake right behind the throttle body mount, because that's still attached to the manifold.

Any help would be appreciated. :)

Thanks.

Are there universal fuel lines available with those quick disconnects? This motor will be going into a custom application, so I'll be running my own fuel lines. For the sake of cost savings, I may wind up utilizing the factory rails instead of upgrading to aftermarket, so I'd like to know how best to interface with them.

Thanks

Most quick disconnects have fittings for two sizes of fuel lines 5/16'' and 3/8''. Just use one of those two sizes for ur hose.

The top hose is for the Evap Cannister Purge Solenoid.

For an LS3 this is the PCV foul air hose.
