I've had mogas in my fiberglass tank for a couple of years now. Now I get a warning from my kit manufacturer to not use mogas in my fiberglass tank. (even though its an isuzu equipped kit). No reason, just not to do it. Anyway, I cant SEE a problem in the tank. It all looks clear when I drain it. Its not leaking. So whats the deal with mogas in fiberglass tanks? And what do I need to do about it now?
