How to Effectively Service and Repair a Fuel Injector on 2004 Jeep Wrangler?

Servicing and repairing the fuel injector begins by releasing the grip of the fuel injector on the fuel rail. After that, slide the fuel injector(s) onto the fuel rail and use the retaining clip(s) to keep them in place. If you are installing the same injector(s), always use new O-ring(s). Apply a little engine oil on every O-ring of the injectors before you install them. Once done, mount the fuel rail again, start the motor and inspect for leaks.
