Hey guys, looking for info on this, hoping you can help. Busted the hose right off the connector going from the connection labeled "E", which i elsewhere saw was for the "breather pipe."

My previous understanding of a breather pipe tells me that i could easily patch it and not worry, as there wouldnt really be any fuel running through it. However, i was apparently incorrect. Patched her up, went for a drive and... fuel is leaking. Any further understanding of the system you guys could give me would be much appreciated.

Also, where the hell does the other end of the pipe lead to? Worth knowing since i may have to replace it...

For details: Its an '02 A4 1.8TQ. Has that funky fuel filter thats 5 times as much as the others.
