Need Fuel Injector Rail
Can someone please give me advise on were to purchase a Fuel Injector Rail Assembly for a 1989 Jeep Cherokee?
I just started up my jeep today, smelled fuel, and then opened the hood and saw that gas was spraying out from the Fuel Injector Rail Assembly.
So now, I am looking to purchase this rail immediately and replace it so I can drive my jeep again.
Also how hard is this rail to replace and do I need to replace the fuel injectors or any other fuel items once I see the rail start to leak?

Well it's easy to replace, not all that much involved in doing one. Your injectors should be fine, they shouldn't have to be replaced, but the injector seals, that depends, read on...
But first... Where is it leaking? Is there a way you could try a re-seal the injector tops if it's leaking from there? Is the rail cracked somewhere? The Fuel Press. Reg. AFU and leaking?

O-rings top of the injector's. Make sure to use o-ring grease when you put her back together.
My last two heep's suffered the same problem.

On my F350, JB Weld is currently sealing two leaks in my fuel filter headder. I did it two years ago, and no leaks to date.
I wouldn't try it if the culprit of the leaks is o-rings, plastic, etc...but if it's the metal rail that is cracked- and fuel is leaking from that crack- JB Weld WILL fix it. No doubt.

JB Weld will fix anything besides a broken heart; I beg to differ with the above, kindly.

Verify exactly where your leak is coming from. I agree that it is most likely coming from a bad injector O ring or a failed regulator. I've never heard of a fuel rail breaking or cracking unless it has taken a pretty good shot from an outside force. So, replace your leaking O ring, regulator or get a fuel rail from one of the guys. Problem solved.

i to am having the same problems, the fuel seems to be coming out between the rail and the injector itself, i went and bought what i was told was the cure which ended up just being the o rings that seal the injectoer in the head i'm still searching for the solution, i am new working on injected systems so i have no idea of what i am doing, and the haynes manual isnt worth the paper it is wrote on, ant ideas or information on this
