Thread: Need help identifying part

I recently purchased and 05 Grand Prix GTP, as I was inspecting the lines today I noticed there was a small crack in the assembly where the bypass actuator line, and the vacuum line connect. Does anyone know what the part is called?http://i1214.photobucket.com/albums/...2213/bbv-1.jpg ( Found a Google picture but no name for the part, part is the one in top yellow circle.)

Thanks a lot guys, I spent a good while trying to find it, even went to the local parts store and the guy had no idea what it was.
