3800 series ii intake manifold white bent tube
So I am replacing the gaskets on this (in)famous manifold(the improved ERG version was replaced years ago), putting it all back together, but I can't figure out what the deal is on this white plastic tube.
It clips right down the center of the upper gasket(legnth-wise on the plenum side) and wasn't connected to anything (that I could tell) on either end.
I have search all over the web and have seen the question asked but never answered. My new kit didn't include it, and I can't find the part anywhere. I checked that awsome exploded veiw of the 3800 posted by Danrod963 a few years back, but it doesn't appear there either. Definitely no mention in the manual.
Can anyone tell me:
Which direction it turns or what'* it connect to
What is it called(so that I might find a new one)
Thanks in advance,
