We wanted to be able to polish and transfer fuel between all our tanks, have gauges to see how full the tanks were, and have easy access to valves, fillers and gauges.
Beatrix has 3 fuel tanks: a new aluminum starboard(100 gal) tank, the original steel port (60 gal) tank, and a new aluminum port "day" tank (54 gal). She also has a large Racor 900 filter for polishing and a Racor 500 for final filter of the engine supply. A continuous duty Oberdorfer gear pump is used for transfer and polishing with a light duty Walbro for priming, bleeding, and backup. We also have an external pickup (discharge) to allow us to pump fuel from (to) an external source such as a fuel drum or another vessel.
The system is built into an aluminum frame with the most used valves and gauges accessible from the a panel in the aft cabin. Less used bypass and shutoff valves are in the engine room just behind the sliding door.
In 2012 the fuel control system was expanded to allow for automatic shutoff when transferring fuel to the day tank. This system also will enable a "tank full" alarm when any tank is being filled and allow for timed polishing. Very sensitive 02.5PSI pressure switches are used to tell when the tank is full.
