I just replaced a head in a 22RE. Now the first fuel injector is leaking from where it joins the fuel rail. Injector 2-4 don't appear to leak. After the fuel pump stopped the injector continued to leak for another couple of minutes. What did I do wrong when I attached the injector into the rail?

It might be cocked in there. I trust you lubed the o-rings with FUEL, not petroletum? Gotta hold your mouth right when you reinstall these things.

I didn't lube them at all. Are the o-rings messed up? They came with a new set from RC when I got them cleaned. My gasket kit I got also has some. Should I swap out them o rings or do you think they should still be ok? I pulled them a couple years ago and didn't have a problem, but they must have been still lubed with gas.

By all means, if you've got some new to spare, then swap them out; I would.

No lube is most likely your problem. Mine leaked because I forgot to lube it. FSM calls for a light coat of fuel.

Any more tips. I'm having a hell of time getting this to work. I've taken it off 4 more times. Now I've lubed the seal and replaced them with the new seals. It was the first injector then the fourth then the second then the first agian. What am I doing wrong?

I had this issue with the connectors to the injectors were pulled too tight, the wires and clips were actually pulling the injectors out of whack. Make sure the harness for the injectors lay down nice and easy, you should be good.
