Folks, I have a leaky fuel rail on my 02 Liberty. I replaced the old engine with a remanufactured and I think it may be damaged. Can this be fixed, replaced, or is there a work around? Any help is appreciated.

Input is appreciated. Restoring the liberty has been a welcomed challenge that I've enjoyed so far.... except when I see that parts aren't available. As for the fuel rail, I noticed online that some places may offer custom fuel rails, not sure what the cost is for that, we'll see.

Since you said upthread 3.7, I would take a hard look at the rail to injector connection (socket) as it were. The injector has o-rings on the top of it and if one is nicked or dry-rotted, it can cause leaks. Can you isolate exactly where you see the rail leaking? Helpful tip - if it is an o-ring, do them all while you have the rail pulled off.

It's not any of the fuel injectors. It's the front part of the rail where it swivels a bit. Looks like it's crimpted.

Is it here?
It would be safer to replace it to prevent a fire.

I have redone my valve covers, because of an oil leak, and to get to them everything on top was removed. I didn't even know I had a leaky fuel rail until I got to that point and you could smell it with a little liquid present. I ended up getting one from 1A Auto or Rock Auto (don't recall) and no issues after getting everything hooked back up. Not difficult but just buried a little. Supposed to have a "special tool" (made of plastic) to unhook I believe.
