I drug out my more complete pic. from the FSM.
This is 2nd hadn info but what I was told in Trade School is that the Metal Edge Filter is there becaues over time pieces of the inside of the Fuel Injection Lines erode and some times break loose and that the Filter is there to deal with them.
But this must not be a major issue as most Diesel Injectors do not have that feature.
A diesel parts guy in Germany told me that but he was not sold on the idea that they needed them in the first place. I don't think it's a major issue either. I recently had a few sets for an OM606. None of them had the edge filters, but they all had a big feed holes. New manufacture (of older design) injectors don't have them either. And, if we account for the size of the passages inside, the edge filter can let in particles big enough to get stuck inside the injector.
