All I want to make sure is that I don't have a restriction upstream....if its just running rich I can tweak that.

I guess its probably time to put in my wideband o2 sensor in place of the OE Bosch unit so I can figure out whats going on.

In fact, it does actually look like rubber particles. Possible remnants from pump(s)/accum/fpr?

Maybe I can remove the fuel level gauge and peek into the tank and see if its okay or not.

EDIT: What is the possibility I am doing the test incorrect?
http://www.w124-zone.com/downloads/MB%20CD/W124/w124CD1/Program/Engine/103/07.3-1609.pdf
It mentions:
"Unscrew injection lines and fuel distributor, and slacken at the injection valves; unscrew if necessary".

Does that sound like the injectors are supposed to connected for the test, or disconnected?

Because then I read the OE Bosch Manual:
