injector leaking

[smdv806]

I have a 1993 5.9 cummins. I noticed after the truck had been sitting idling for a few minutes there was a puddle of diesel fuel on the ground. I looked at the injectors and one of them is leaking. The injector line is on good and tight. It is leaking around the injector. Do I need to tighten it down? How do you do that? Or is it cracked or something?

Tighten it once........still leaks: Take off the injector line- look for cracks. Run your fingernail around the end of it. If it snags just a little bit, it is cracked, and you need to replace it. Cannot weld it, but easy to replace. Not uncommon problem.
