If I were THAT worried about filtering. I would probably find a Racor and put it inline with the factory one. Those of us with boats do this a lot. Have a Racor first in line that is 20-30 microns, then the one on the motor have it be a 2 micron to catch what the first one does not.
Using ONLY a 2 micron would clog the system more than one would want generally speaking, UNLESS, you used a BIGGER than normal for the fuel GPH useage. IE a 60 GPH filter when you used at best 1-5 GPH vs the typical spec of a 15-20 GPH filter.
Your mileage as all thing will vary on this topic too. I would agree with turtle tho, the first injectors on the Dmax's were not up to spec for what they should have been. Filtering is not the issue.
