I have read several posts where fuel leaks has occured with both new and old gas/diesel fuel caps. It appears from reading, the FIX is to change the fuel tank as the fuel nozzle opening is bent and a new cap or new gasket for the cap will not stop a leak. I am a bit puzzled by this as my tank is only half full so how does fuel climb almost vertically to escape pass the cap? My wife who drives the car with 3 kids is a very sedate driver. The fuel door is always filled with diesel and running down the side of the car when she returns home. The fuel vent appears to be unobstructed as low pressure air does make it out of the bottom of the vent hole.........SO the question remains how does fuel climb vertically in a half tank of fuel or am I missing something?????????
