ethanol and gas tanks

[RWilson2526]

Can't say I have heard of one rotting from the inside out, but they do certainly rot from the outside in. Silicone sealant goes bad around gas tank hatch, water gets into the fuel tank compartment which has no where to go and sits in the foam against the tank walls. You can get an exact replacement from oem somewhere in Florida. Somebody just recently posted contact info.

fiberglass tanks break down from the ethanol fuel. The resin turns gummy and gets into the carbs. If it sits long, it will solidify and ruin the carbs. I had a 4 stroke Mercury(Yamaha) on a whaler gum up. It actually stuck the intake valves open. I was able to save the carbs and get the valves free, but it cost him some $$$. . luminum can be any coloracrbs for that motor were over $600 each(4 needed). If you have a fiberglass tank, get rid of it before it destroys your motor.

BTW, are you sure you have a fiberglass tank? they are usually red in color. Poly tanks(OK with ethanol) are off white or light brown

Okay perhaps it is a poly tank. It's off white. Guess that's much better than the fiberglass ones!! Thx for the info!!

Mine was an 88 powerhead mounted on a 98 mid section. An 01 is a FICHT engine most likely.
