many microns the spin on fuel filters on the engine are.  One person thought
2 or 4, another said they must be around 5 microns.  How to find out for

    *  One fellow, with the same engine on his boat, made a recommendation.

the spin-on every year, and you'll be fine.  This is what he's been doing on
his boat for years.
    The reason for the 2 mic Racor is to keep any junk at all from getting

    As with so many of these things, there's a variety of opinions and,
