Mine also leaked but operating a few times stoped it. I had never in 112,000+ miles had water in there so I guess I am fortunate; maybe because I change the fuel filter every other oil change, I know overkill. I stopped using the dang drain anymore because it always seemed to leak afterward. I use a turkey baster to empty the fuel filter canister for the fuel filter change and put fuel in glass jar to check for water and have found none yet there either.
