I use the the Fuel water separator with a plastic separator. I have a small tube attached to the separtor to bleed off any water ect. I have made a practice of draining after each use if needed as PM. I have had water in the tank which made it to the carbs and it was not a pleasant trip back from the 4th behind Seatow. Hope this helps. I run a Yamaha and the fuel filter they sell is solid I feel better, however using the separator.
