[urq] Fuel tank "bong" noise...

[Louis-Alain Richard]

... it was indeed a sticky ball valve. I clearly heard the ball drop in
its housing when I removed it from the car.
 
And about the fuel gauge, the specs in the Bentley to adjust the fuel
jauge are the ones for the Coupe's 60 liters tank. There is no spec for
the urQ 90 liters tank. So the only way to adjust it is with a full tank
and a empty tank or with the sending unit out of the tank.
