Here is the continuation of my earlier post. Since I have two new pictures, I put them in a new post.
I cut my used fuel filter open today. The filter came from our 1996 E300D (W210, OM606NA, 265000 miles on car, 1 year and 8400 miles on the filter, mostly B20 biodiesel with a little D2 and a little B100 thrown in).
I used a cutting wheel and my Dremel tool to cut through the casing of the filter. A large-size copper tubing cutter would have done a cleaner job but I don't own one big enough. In any case, the only thing in the filter was a little dust from the cutting wheel. As the photos show, the filter was in near-new condition and could easily have gone another year or more.
I would imagine that one could hire a lab to wash out and centrifuge a used fuel filter and no doubt find something but it certainly wouldn't be much by the looks of it. Anyone have such equipment at work and would like an after-hours project I can send the filter pieces.
All this really means, of course, is that I haven't found any dirty fuel vendors . . . yet.
YMMV.
