Marty my brother have had problems with C11. When we fail fuel check we went back to pits and dumped fuel and replaced with fresh C11 only to fail again. Tech guy asked, "did you replace the fuel cell foam".....uh no we didn't. Go back dump the fuel and remove the fuel cell foam and then we passed.
We permanently switched to C12 only to pass fuel check. Since then we have used C12 in pails and C12 from underground tank with no failures.
