Hey whats up guys, I have a problem. Today I was cleaning my fuel rail and I took out my injectors. I heard to never put back injectors with the old o rings is that true??? What is all that I have to do before I connect my injector to the fuel rail, do I dip the injectors inside fuel to clean them up??? Tell me everything I should do before i install my stock injectors?? Thanks u guys and have a nice day. Peace
