My wife has a Fiesta diesel 2012 model.

She can put the fuel pump nozzle into the car fuel tank pipe, but when she has finished refuelling, she cannot get the nozzle out of the tank; it sticks solid as if held in a vice.

I don't have the same problem, so it's got to the stage where I have to fill the car for her, which is very inconvenient.

I've tried to teach her how to do it, and unsuccessfully tried to work out why I can do it and she can't, but she cannot get the hang of it.

Although she's very cack-handed I cannot believe that she's the only one that has this problem. Is it a known issue and is there a knack to it please?

Any help would be greatly appreciated.

Many thanks.
