I checked.
It had moved...the flap piviot was at 7 O'clock. Interestingly the car had become increasingly difficult to fill, blowing back a bit of fuel as it became full.
Slid it back to 12 O'Clock. It is very easy to turn, finger pressure is enough. It will be interesting to see if it is easier to fill. If it is then a spot of Epoxy may be indicated.
Could this be the root cause of all the filling problems reported? It certainly explains why dome cars are easy to fill, some are not and some change...
