Here is one of many articals I have read about ethanol in fiberglass tanks:
Ethanol is a blend of gasoline and ethyl alcohol. Ethyl alcohol is an excellent solvent and is hydroscopic, that is it adsorbs water. Acting as a solvent, ethanol can damage the sealants used on older fiberglass fuel tanks. The dissolved sealants can be ingested by the engine which can cause damage and fuel leaking from a tank into the bilge is a fire hazard. Fuel tanks built of other materials are not immune to having a problem. Ethanol has a cleaning effect on tanks that releases fine metallic particles which will pass through most fuel filters. The dissolved metals will clog fuel injector nozzles and carburetors. Ethanol added to a fuel tank contaminated with water will cause expensive repairs. The water in the tank will combine with the ethyl alcohol to produce a noncombustible layer of liquid in the tanks that will stop most engines cold.
I understand plastic tanks, will fix the problem...but, ethanol can still harm an engine.
NOTE: You can find gas without ethanol...(check the net for local gas stations that sell gas without ethanol.) Over the next few years all gas may have ethanol.
