purge valve

I was replacing the purge valve on my 2000 Beetle and this hose snapped. It was attached under the hood right above the purge valve. Any ideas what it is and where it goes? How to replace? The second pic shows where it leaves the hood. Thank you!!!

Hey all. Having a few issues with the bug and from what I'm being told its my purge valve. Ive also been told its pretty easy to put a new one in yourself while I'm not real car smart I'm pretty good at watching something or someone do something and be able to do it myself. Now has anyone...
