POSSIBLY.....think about it....ethanol fuel (propagated on us by the feds) is not only very corrosive, but has a VERY short life span....probably more on the line of 6 weeks to 2 months (NOT 6 months) Alcohol free gas could last considerably longer and can be found at many stations. Anyway, not wanting to pull the gas tank, is understandable, but usually is where the problem is...but if you are running a carb the ethanol will evaporate at a rate great enough to dry the float bowl in a month or less and corroding the metal as it does, junking up the carb. Oh, when you do pull the tank, don't be surprised when you shine a light into it. Also, i wouldn't try to clean and "reline", unless new ones are not available. If you are NOT fuel injected, by all means find a station with ALCOHOL FREE gas, either regular or hi test depending on your needs...your car will thank you for it. Just my opinion guys
