How to Install a Fuel Injector in a 3.7L/4.7L Engine on 2009 Dodge Ram 1500?

If you are installing new injectors, you don't need any new O-rings. Place a small amount of clean oil onto the injector O-rings before assembly to make things easier. After that, push the fuel injector from the side into the fuel rail assembly. After that, fasten the fuel injector retaining clip with proper pliers. Attach the fuel rail assembly after the injector is secure and run the engine to spot any leaks.
