AccordTR,
So I started dicking around with those plastic tubes and the just moved the one that broke on you car and and mine just snapped in two also. While yours was on the left and mine was on the right side of the engine. See pic.
So from the parts description it looks like that tube is a crankcase vent tube so I guess it's under very little pressure. I'm going to try a jury rig patch to see if I can get away without replacing it for now.
The car is a 2013 so it's way out of warranty.
