Do you have a water separation filter, like a Racor, in your system? It should remove water from the fuel BEFORE it gets to the fuel filter. I would suggest that water in the fuel filter is problematic. The Racor will likely have a glass bulb in which you can see water at the bottom. A valve at the bottom permits the water to be drained.
