The prime reason for mis-fuelling is that the diesel pump filler nozzle is larger than the petrol nozzle.
So, both the petrol and diesel filler nozzle will fit.
Diesel Key has been discontinued - replaced by Diesel Fill which is more robust device which fits a greater number of vehicles.
We only have Diesel Fill for vehicles with screw-on type fuel caps but hope to extend this to bayonet type fuel cap fittings in the near future. If you have a screw in fuel cap and the filler neck does not have a flap Diesel Fill should fit your vehicle.
******Applications are vehicle specific so before you purchase this please contact us in order to check the compatibility of the Diesel Fill in your vehicle.
