Fuel rail leak at the injector

So, my 2003 Tj just started leaking where the fuel rail connects to the #3 injector. It looks to be right at where they clip together. Any ideas on what exactly is causing this? Is it the injector, fuel rail, or an o-ring of some kind that needs to be replaced?

I would suspect the o-ring.

Remove the injector and see if the o-ring is torn or if its dirty around that area causing it to not seal properly.

You'll need to depressurize the fuel system to do this.

The unsafe way - push the schrader valve on the fuel rail and let the fuel squirt out.

The safe way - pull the fuel pump relay under the hood and let it run itself out of gas.
