Rodger,
For what it is worth, I have two 1000 liter tanks, one starboard and one
port. The plan is to fill one, polish that into the other and then fill the
now empty tank. I then fill the day tank from the "clean" tank. As fuel is
consumed, I then transfer from the dirty tank to the clean tank for balance.
My transfer system is fed by a manifold and it also pumps to an outlet
manifold. Each manifold has three ball valves, which allows me to pump from
and to any of the three tanks. I use a large RACOR centrifugal filter and a
surplus US Army helicopter fuel transfer pump.

The sediment bowl on the Shelco filter I put in for my fuel polishing (or
Pre-filtering, whatever you want to call it) system doesn't drain
completely. I took it out of the boat today, poured off the fuel (Not a
drop of water BTW), and scraped out the stuff in the bottom:

Wow. I was saying a while ago that didn't think the system was necessary
for the cruising I do now. I would have agreed with anyone who said it
was a hobby affectation. I still wouldn't say "necessary" is quite the
right word but I sure am glad I have it just for tootling around in Maine.

This is the left overs from about 100 gallons of fuel purchased during the
year and isn't all off it since a gust of wind blew the plate over. About
half of the fuel was road diesel purchased at a high volume gas station.
Sure, the Racor could have dealt with this stuff and I could have dealt
with the Racor but, why? There was not a speck in the Racor bowl it
looked just like it did when I changed the filter and filled the sytem
last spring. Having this crud removed from the system in a way that makes
having to deal with it's disposal underway vanishingly unlikely is great.
