Need help whats this part???

I have a 1994 lt-1 camaro and I accidently broke the plastic line that goes from the left side of the intake where the injector wires hook up. There are two lines one goes to throttle bodie (short line)and the other goes to th other side of the intake and hooks up where all the big fuel lines go(long line). I broke the long one that goes to the other side of the intake (long line). No fuel or anything came out so i dont know what it is and i need to replace it but dont know what it is called.

I think your talking about part #1 in this picture ref shoebox " http://shbox.com/1/1995_evap.jpg " It goes back to the charcoal canister its used to suck fuel fumes from the canister into the intake when the solenoid picks. Its hard plastic and gets brittle , I cracked mine doing my cam swap. Find a piece of hose that fits over it and fix the break or replace it with a piece of vacuum hose. If you leave it open you will start smelling gasoline fumes under the hood or when parked in a garage. Choice is yours, people that don't keep cars stock ofter remove the EVAP system and put up with fumes or vent them out back like the old days...

Thanks bobdec just what i needed to know. Guess ill be getting some hose to fit it. I just wasnt sure if anything ran thru it before i tried to fix it.
