Or are you looking for the piece that goes under the throttle body and joins up to the vapor hose (part# 10228934 in the diagram)?

I'm not really looking to fix the hose, it has two big cracks in it, i'm looking to replace it entirely. Ya it is the hose that goes under the throttle body.

ok, just to clear:

3 plastic lines come out of the fenderwell. 2 go to the fuel rail. The third connects to a length of rubber fuel hose (hidden inside the corrugated sleeve that protects the lines). The other end of that rubber 'vapor' hose connects to the thin hard plastic line that has several bends in it allowing it to pass under the throttle body, attaching at the bottom of the purge solenoid. The part # for that thin plastic line with all the bends in it is 10228934.

So I swapped out the plastic lines that came out of the fender wall and the line that went under the TB, and the code popped back up again. When I did a scan, all the cycles were good except that the o2 sensor cycle still said incomplete. Where do you think I should go from here?

Ok so I went ahead double checked the purge solenoid, and its in fact stuck open again. Im going to take it to autozone and swap it out since it came with a warranty.
