Has anyone had problems with the gas cap leaking? Every time I drive my car, I notice dirt all around the trunk area. The cause, I discovered yesterday, was that gasoline is literally coming out of the gas cap. I have concluded that the O-ring is not being compressed by the cam lock mechanism. I tightened up the lock nut as far as I could but it still seems to just "flop" over with little resistance.

Does anyone have a fix for this? How about an upgraded cap (screw type) that fits to the body / bolt pattern?
