CM2250, fuel leak mystery, please help!!

[JMBT]

   Here is what I am considering to be the faulty part that was causing the leak, the line that runs from the rail to the injector supply tube, at least it is the only thing I could find that may have caused it. Notice how small the corrosion or fretting was, and not even really on the sealing area of the tip. Or at least that is what I thought. Some of the others looked just as bad when I did the initial job, but none have started to leak yet. I thought they all still seemed good, so I ran over them with the brass brush and re-used. We’ll see if any of the others bite me in the ass.
