Mine does that too. Maybe not as far out as yours though.
I kinda watch it from time to time, seams to work its way up about an inch.
Generally just check it and push it down during fuel fills. Have read of some owners
pinching the top of the dip stick tube a bit to hold it in a bit better. Haven't got too excited
about trying that myself.
