Water Separator for E85 Fuel Cell

No issues for years with the ball valve.The tank will go under pressure,slight vacuum as temps change,but keep in mind,if the car only sits for a couple of weeks at a time,you don't need to do anything.As far as the separator goes,I don't think it would work unless your talking about the big dessicant filter type.I live in probably one of the most humid regions in the country(it sure feels like),and its just not a big issue.Some guys do like to run an additive such as starbrite,B.G.,etc., just for piece of mind.We just run it pure and love it!
