Wow!!!!!!!!! Never had a situation where the station didn't have a nozzle that would fit through that protection device. If you have to use the funnel (which I do carry in my trunk) you would be needing fuel like right now with no other choice as there are many more stations with appropriate nozzles. I think the protection it offers far outweighs the hate for it that is preached on this forum. Also if you remove it and introduce gasoline into the car and it fails your on your own. What's the big deal?The thing they stick in the fuel fill neck to prohibit the use of a non-diesel nozzle, no idea how it is supposed to work, as they also sell a funnel to be able to defeat it since it often will not allow the car to be fueled up even with diesel.
