Over time, it will break down. If I am not mistaken....foam in a cell is supposed to be taken out and replaced every year. It will get nasty if it breaks down....seen one like that...not a pretty picture.

Foam is a good thing. It will help keep the fuel from sloshing around in the tank (and away from your fuel pickup) and most importantly, since it acts like a giant sponge, it will hold at least a good portion of the fuel in your tank after some idiot rearends you and splits your fuel cell open. Yes, it will leak but you won't lose thirty gallons of alcohol in a deluge, pouring out and under your car as you try to get out. Change it every year or two and you shouldn't have any trouble with it breaking down and plugging filters.

Instead of foam use WHIFFLE BALLS. They never break down.

I use the foam. Helps keep fuel from sloshing around. I changed it this year, only had one year, but I changed it anyway. On my stock I am going on the 5th year with the same foam. It's gasoline powered though.

I've seen guys using drain tile tube. It's a product that's used in home construction, buried under ground around the inside of the footings to allow for basement moisture escape. It's a black corrugated tube, about 3" round with holes in 4 sides about every 2" or so. Cut them to length and stand them vertically inside your cell, until there isn't room for any more. Your fuel can't slosh through this stuff, and it won't break down. A lot like the whiffle ball idea, only tubular. I just heard of the idea at the end of last season, so I haven't done it yet, but it's on the list for this spring.
