F250 injector leaking

My injector is leaking on the outside on top of the engine. How do I fix it? I have a 1993 F250. Thanks.

go to your local diesel shop, there will usually be one in the area that carries parts for perkins, kubota, powerstroke, cummins and several more and tell them that you need a fuel return o-ring kit. It will come with new o-rings, the plastic pieces that have the nipples on them that the lines run from injector to injector and a section of rubber fuel line and all of the clamps needed to fix it, the orings inside those plastic pieces start to leak after a while, if you let it get too bad it will lose its prime and it will not start, after you change them you will probably have to do a little bit of bleeding on the system but its not bad, it should only take you about an hour to do
