You want a 2 micron filter as the secondary or tertiary. Clean fuel without particulates is what you want. The clearances in the injectors will not not put up with particulates for long.

10 microns is almost 0.0005" - and injector tolerances can be 0.0003"

Better safe than sorry - the downside is you may have to change the tertiary filter more often. Cheap insurance.

My Westerbeke 4-107 has over 6,000 hours and no rebuild, and for 35 years it has always had three filters, coarse medium, and fine (2 um).

So, with the data available to me, I like 2 um filtration.
