    On my 2001 Tacoma the air drain hose coming out of the evap system is just flopping around. There's a rectangle flange at the end that suggests it's supposed to be affixed somewhere, like maybe a hole in the body, but I can't locate an appropriate sized hole.

    Can someone point me in the right direction?

    that grommet fits into a hole within reach of where the hose hangs at, just have to crawl under there and look

    might even go in the frame rail somewhere, you just have to figure it out but please reply when you do and show us where it goes

    On my 2.7 motor (with the evap canister on the driver wheel well under the hood), there is a short rubber line from the evap port that goes straight down to a small bracket where it changes to a short hard line that also goes straight down along the wheel well to another little bracket. Then a much longer rubber line with several bends in it disappears into the horizontal surface of the driver-side frame rail.

    While researching why this air drain hose goes into the frame, I found this thread. For the sake of others searching, I thought I would post the fotos of where this hose is supposed to go.

    I'd still like to know why there needs to be a drain for air, and why it needs to go into the frame.

    ". . . I'd still like to know why there needs to be a drain for air, and why it needs to go into the frame. "

    Wild-ass guess here, but this appears to be a type of 'air' venting.
    However this 'air' likely contains gasoline vapors, and is therefore flammable.
    Inside the frame rail is the safest place (no source of ignition).
