S-series fuel gauges are noted for going bad. Sometimes need to replace whole pump assembly to get the sending unit, expensive. Also note that in Florida area some gas was recently found to have high levels of sulfur, eats up the sensor windings. Gas companies are paying to get these fixed. Worth a look if you live in that area.
