I smell gas very strong inside and outside of my car especially if the gas tank is 3/4 full or more. I see no dripping under the car. I see no leaks around the engine compartment. I think the leak may be on top of the fuel tank. Are there any rubber hoses between the gas fill and tank? Ethanol 10% rots rubber fuel hoses badly. My guess is that a vent or fill hose is rotted. How do I get acces to the top of the tank to look?

Thanks,

Ed
