Water Separator for E85 Fuel Cell

Been running E-85 for 5-years now in our drag cars,we don't have aluminum tank's,but about the only way to keep moisture out of any fuel cell is with a simple ball-valve on the vent hose.It also helps to keep it out of the elements while sitting dorment.Just be sure if it does sit for long periods of time to run it a little every couple of weeks.If you are using this fuel in a street car that gets driven every so often,you'll be fine.I guess we've been lucky over the years,never had any issues with water or corrosion like all the other horror stories I've heard.
