MF 261 fuel leak

[markwmo]

I have a "98 MF 261 with the Perkins AD4.236 engine. I have a leak or drip at the top of the rear injector. I think it"s called the drip rail but it"s the pipe along the top of the four injectors. There is a bolt and steel washer on each side of the pipe fitting. The leak appears between the bottom of the fitting and the large nut at the top of the injector. I have replaced both washers but can"t get the leak to stop. Anyone have any thoughts or suggestions? Thanks!

Check for a pin hole in the line, and be carefull that is high presure.

Check for a crack near the banjo fitting, or a thin brazed spot. This is a low pressure return line.
