    Hello folks,

    I just got done swapping the motor in this 2010 Prius, and I ended up with this 1 orphaned hose fitting that I can't find the hose to plug onto. Can you guys identify what this is and where the missing hose might be?

    It's that tube that runs across the back (right side) of the valve cover, underneath the wiring harness. I can't for the life of me find a hose to plug onto it.

    I took a picture of my 2011 Prius to show you the hose that you are missing. Hose.jpg

    (It's for gas tank vapours I think, routes them to intake manifold.)
