One or two people mention having small amounts of water in their filter bowls, which they drain regularly.

This means they have got water in their tanks. They therefore have the ideal environment for Bug growth. If they have mild steel tanks, they also have the ideal environment for the bottom to rust out of the tank.

There is absolutely NO substitute for eradicating water from your tank. This should be part of your annual service of the boat. However many manufacturers make this almost impossible to get access.

However this is a major safety issue and the cause of a significant number of calls for help.

My tank has been cleaned twice, once by a pro and once by me-both times after cleaning as good as it was possible to be after access through the fuel gauge hole. I believe the water gets in through contaminated fuel or condensation. Pre the last clean clean half a cupfull after 15 hours running. So far this year 18 hours running, some in heavy seas to shake it all up, barely half a teaspoon. As I have about150 litres in the tank I expect I shall wait untill it is less full before pumping out and cleaning the tank interior again.

I agree, and the best way to avoid the problem is for ALL fuel tanks to have drain valves at their lowest points. Designers please note.
