Re-fueling issue
Quite a common problem. Not sure if it's because of the pump pressure nowadays or what. It might have something to do with the diameter of the nozzle since they switched to a smaller one after they started installing those in tube anti siphon things.
Usually when I fill mine I stand there and hold the lever and listen carefully for it to start up the filler tube (think filling a glass with water and how the tone changes) once I hear that I stop pumping.
