That is the stuff you are probably seeing. Ours did the same thing for quite a while but finally quit when it ran out of loose material sloughing off. When taking a sample from the sump to test for fuel contamination you can mitigate the problem by making sure you open it wide and quickly draining out a good bit of fuel and then closing it quickly. This ensures the flow rate is maximum which tends to flush out the black stuff that has settled in the sump cup. -------- Thom Riddle N221FA Allegro 2000 912UL N197BG FS1/447 -------------------- Scratch any cynic, he said, and youll find a disappointed idealist.

I inspected the inside of the tank (I thought thouroughly) after this started happening and didn't notice anything around the strainer, but it may have been purged before I looked. My sump is the kind that pushes up with a little rod attached to the cup and is spring loaded. It seems the particles are lodging between the two surfaces that seal against each other. It's kind of a pain to remove it each time this happens. Maybe I'll be as lucky as you and this will stop in a short period of time. I'll keep you posted.
