I bought a set of used 30# green top injectors awhile back. When I put them on I noticed a small fuel leak from #3. I just pulled off fuel rail and noticed that all O rings from injector to fuel rail are annialated.. Everything went on and off smooth and Ive done plenty of injector swaps. Not too sure why this could have gone so wrong. Anyway, does anybody know where to get a set of 12 Injector O rings for our cars? Thanks Rich
