Hey all, I’ve got a 1990 Cherokee with the 4.0. I have changed injectors, and orings. I can’t get the thing to stop leaking. I’ve been very careful about removing and installing them with grease. It’s leaking from the top end where the injectors plug into the fuel rail. It also seems to be leaking from near the regulator on the front end like it’s actually cracked or something. Is there a better fuel rail option? I see them listed for later yet but not for 87-90. TIA

Better? I haven't seen one. Are you sure the rail itself is leaking?

There are a bunch on eBay. Prices are all over the map. Some include injectors. Here's one to start your hunt.

Not saying you should buy this, but it will give you a starting point.

When I swapped out the injectors on my '88, I also had a few leaks at first. Make sure the ports on the rail are clean. Put the injectors into the rail first. Make sure they are fully seated. Then push the rail with injectors into the manifold. The mounting flanges should sit flush with the manifold. Give the rail a little wiggle to make sure it's seated before you bolt it down.

I have Renix fuel rails. I think the shipping might be high cuz of the length?
