I also have a vacuum gauge on the filter system to keep track of filter condition. If vacuum gauge shows need for filter change I just turn the lever and run on new filter and change at next opportunity.Very easy to change out as it is screw on type filter.

I also have the ability to polish the fuel through the same filter system which I will do for about an hour after filling the tanks.The 2 micron filters can be difficult to find so I order 8 at a time. Never lost engine due to poor fuel or water. Filters are cheap insurance.

Ed-  I am redoing the fuel system on the boat right now.  I'd love to see/hear a bit more about your setup that allows for polishing.  Thanks!
