unknown line/pipe quick question

[matta]

I am in the middle of installing the engine/trans into my gsx. There are 4 lines coming out the passenger side underneath the car up into the engine bay. I was wondering if someone could ID the 4 pipes that these are.

Im almost positive that 2 are for the rear brakes and two are for the fuel line/return. Im just not sure which one is which.

the two that are the same size and connected are brake lines. The one going to your fuel return..well that's your fuel return. The one dangling all by itself there in the pic is your evap line that catches vapors from the tank. You can plug it if you're removing your evap system

I connected a 3/8ths(?) rubber hose to the fuel return coming off the rail, tried to see where it routed to, I see where it turns into the metal pipe, but I didn't see where it went. Im guesssing its one of those going to the back

So, the pipe that I have marked with yellow tape can be capped? thanks!
