 Topic: 8070 fuel leak

Noticed a small leak on #1 inj line. The parts breakdown shows several pieces - dust shield, hold-down washer, nozzle & holder assy, and sleeve/nut assy.
Where is the most likely cause of the leak? It's not much more than a seep right now.

It looks like the leak is below the sleeve and nut on the nozzle/holder

have the injectors been "rebuilt" recently? I have seen several times where someone attempts to rebuild the Bosch/American Bosch injectors, and they don't lap the mated surfaces correctly or at all. The holder will leak fuel, and it will look like fuel is coming out of the injector hole in the head. If line is leaking under the ferrule you can cut line off at the crack, and use a new ferrule, but the bend at the nozzle end is pretty tight. Good luck, Ed.
