Hi everyone. I was replacing my oil filler tube on my 2000 996 cab, and I broke one of these hard plastic lines off of a 3 way split. I went to see where is was connected and the whole line came out in my hand. can anyone identify what this part is, where it goes, and any part numbers to fix them? thanks so much in advance!

I believe that one is part of the SAI (secondary air injection system). It goes from that "T" in the photo to the SAI valve which is under the left bank plastic intake manifold. You may be able to get to it by removing the alternator and leaving the intake manifold bolted in place. Otherwise it's impossible to access.
