Could be any one of the fittings you can see here, since they would all obviously leak on the bell housing. Seems like you checked over all that though. You might double check it, maybe even the #6 injection line is a little loose, though it should miss while running.

Also check the return line behind the head. Mine did the same thing, but I could see a steady stream of fuel when it was running.

Mine drips a little fuel from the clutch housing too, I THINK it is one or two injectors just barely leaking, running down the top of the head and then dripping off the back of the motor.It gets lost in the tappet cover oil leak, something in the front cover leak, and whatever other crap drips under there :banghead:
