Hello. The older Jeep injectors are known to eventually leak out of a seam as they are a metal body and plastic top. It's possible it's an o-ring but most likely is the injector itself. If you change out this one injector it would probably be a good time to swap the whole set for some of the common "upgrade" ones. As mentioned the 746's from Volvos are good. They are basically the same as the more common Ford 710's except they use the clip but on the top like stock XJ ones. But it is suggested you upgrade your fuel pressure regulator to a 49psi one to get the most out of these. The 703's are the most common upgrade even for renix.
In any event you should do SOMETHING soon as fuel leaking near hot exhaust is never a good thing. I'd find the closest junkyard and grab a stock injector to put in there for the time being regardless of your final choice

Injector Leak..
I would start with replacing the o-ring...But if you can afford to do the upgrade O-rielly's auto part's is a good place to start. At least go to one and ask question's about your jeep's issue's..If you start making the repair's take your time and be sure everything is spot on. Then double check!

Basically to upgrade a renix XJ to 49psi fuel pressure you need a fuel rail from a 91-95 XJ and a 49psi fuel pressure regulator which you can buy new or get one from a variety of Dodge/Chrysler cars at any salvage yard. Part #4418850
