FuelFix is a gasoline storage container with a lower drain valve, allowing users to easily remove ethanol and water that has separated from the rest of the gasoline. When water gets into gasoline, it draws out the ethanol in the liquid, creating a separate mixture that can severely damage engines. FuelFix is a high-density, gasoline-safe polyethylene container designed to let users add water and remove ethanol from gasoline in a controlled way, to prevent accidental engine damage. FuelFix has an EPA-approved gas lid at the top and an EPA-approved gasoline valve at the bottom that make it easy to drain the ethanol and water settled at the bottom of the container, so the remaining gasoline can be safely used with small engines that might otherwise be ruined by the regular gasoline-ethanol mix.
