What is this? Help!
1998 Cherokee 4.0L:
Is this the vacuum tube that leads to the leak detection pump (Pic 1). It is on the intake manifold. The diagrams in the parts catalog are hard to match up. I noticed that this rubber elbow is broken(pic 2), Is that a problem? I have no Service Engine Lights on.
I really appreciate all that this forum does. Regards

Thanks, But a follow-up
It leads around the back of the engine behind the vacuum canister to the item in the second pic, is that the MAP?
