I do not have the picture, but I was doing sealing of this tube a couple of weeks ago.
It goes from the pump through the rubber grommet (together with the hood release cable) under dash, then through 10mm hole in the firewall from under dash up to the area under the air vent flap through another 10mm hole far on the driver's side (LHD) in the bottom of the bay under the air vent flap, and to the nozzle.
For those 2 10mm holes (under dash and under air vent flap) you need two grommets/seals (A0009973181) otherwise you will have leaks under dash.
