This happened around 12 month back.
So there I am standing in the servo fuel gun in hand hand click goes the 'don't put that in there' thingy. Like the bright intelligent bloke I am, I scratch my head and continue to try to trickle the fuel into the tank. Mind you I did check and I definitely had hold of the diesel pump. One of the servo staff comes over to see what is going on (probably heard my very descriptive comments and saw my arms waiving about). Between us we give up and I drive home with a small amount of fuel in the tank.
If all else fails read the instructions! Ah!!! the mis-fueling device.
I scrabble around in the glove box and find the ''yellow doover'' for fixing the problem and sure enough click and all is good or so it seems.
Back to the servo for fuel. This time I check that I have the diesel pump and stick the diesel nozzle into the opening.
Then 'click' and

me if I can't fuel the vehicle.
The staff member comes out again and suggests that its a Land Rover and I should expect problems. While I am listening to his view on every thing european the penny drops.
The diesel nozzle at this bowser has been fitted with a ULP spout! I point this out to the staff member who then goes silent. We both check the other pumps and sure enough its only this particular hand piece that is incorrectly fitted with the ULP spout. I then make comment that the vehicle is doing what it was designed to do and protect both itself and the nut behind the wheel from making a grave mistake.
So whilst I have not stuck ULP in the tank (touch wood) you really do need to look carefully when at the servo as they are not the be all and end all of correctness!
