Floscan not accurate

[Delfin]

Just passing on a serendipitous discovery made. I changed filters and suddenly the Floscan started reading much higher than actual, fuel consumption wise. Consulting the manual, a fairly involved process to rid the system of lurking bubbles was described. It sounded like such a pain, I thought I'd leave it be until I got bored and wanted something to do.

Whilst cruising this weekend, I moved the selector on the dual Racors between the polishing system and the engine fuel filter to what I thought was BOTH, but was actually OFF. 5 minutes or so later, I could hear the RPMs dropping slightly, then surging a bit. Putting two and two together I realized what I had done and switched the valve to the correct position. Voila, Floscan problem was solved.

It appears that you can purge the system of bubbles by shutting off the fuel, then turning it back on again when you start hearing the engine starving. Much simpler than the process described in the manual.
