I have always had the foam in my fuel cells because I run it on the street too, but with all the trouble I’m having, I’m looking to eliminate any potential problems. Do I need the foam on the street?
Nope. I will never have foam in a fuel cell again. It was rated for the fuel I used and all disintegrated in 1 summer and ended up leaving me stranded on the side of the road. I finally got it back home and both my filters where plugged solid with that damn foam.
