Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you are unintentionally filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow

•
The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling - other-
wise the expansion volume is filled up.
