Finally got round to doing it,Did you manage to get it back in place? If so, could you explain a bit how to do it. I replaced mine a few weeks back and just put the tube back in somewhere.
So undo the screw at the bottom and side holding the wheel liner in place
Then you will find the plastic pipe feed it down to the cut out section as you can see in below picture, tighten up all screws and job done, Even did a little bit of cleaning whilst i was in there.
