Just food for thought here (not saying that this is your issue), but with today's ethanol blended fuels, the rubber compounds within our fuel system (and any other vehicle built before ~2001) are not compatible and will break down and leak. Not to mention the issue of having steel lines and a steel gas tank. Also, not all states are required to tell you if there is ethanol in the fuel and in others they don't have to tell you how much.
I know that washing and waxing my car with the present condtion of my paint is like polishing a turd.....but it's my turd and I want it polished!
