I had the racor filter with the clear bowl on my last boat, and one day i went down to the boat and smelt a STRONG scent of fuel, looked in the back hatch where the filter is located to see a steady drip of fuel emptying into the bilge from the bottom of the filter, the ethanol had ate the rubber gasket around the drain in the bowl, the filter was less then 8 months old. Although i love to be able to see if there is shit in the gas water dirt etc, after that day those filters scare me.
