Water Separator for E85 Fuel Cell

DFootCuda said
There are tons of additives for this crap gas we get now that will prevent " phase seperation " . I work in the Boat industry and it is a huge problem . Use and additive over a filter ( if you use a filter it has to be 10 micron at least ) . The alchohol also permeates all the rubber in your fuel system and softens it to the point of turning to " goo " . Use an additive to keep water out of fuel , filters dont work too well when water suspends in the fuel any way .

Yes I have read the same thing you're talking about with the boat industry. It does seem to be a much larger problem than it is with cars. My whole fuel system is E85 compatible so I won't have the worry with softening rubber. I'm even getting my fuel cell anodized inside and out to prevent any corrosion issues that could develop. I guess maybe the best thing to do is to use up as much fuel in the tank as possible before refilling and refill the tank maybe more frequently than one would do with regular gas.

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!

Well that sounds promising. I live in Kansas which seems humid, but I've been to Florida and it's definitely more humid there! So if you're not having problems, I can't imagine that I would have any here. This definitely helps!
