The active misfueling protection device consists of a mechanically operated shut off flap and three fuel nozzle sensing tabs. When a 25 mm diameter diesel fuel filler nozzle tube is inserted into the fuel filler pipe, the three sensing tabs depress. Thereby the three sensing tabs releasing the shut off flap into the open position. The fuel filler nozzle tube can enter into the fuel filler pipe.
If a 21 mm diameter fuel filler nozzle tube is inserted in the fuel filler pipe, the three sensing tabs will not depress. The shut off flap will not release, so this blocks the fuel nozzle from entering the fuel filler pipe. The 21 mm fuel filler nozzle tube is used on petrol (gasoline) pumps.
