Cleaning fuel Injectors on the car
This is an amateur demonstration of how i cleaned the fuel injectors on my 5.9 L 1998 Dodge Ram 4X4. The method used was by attaching an OTC 7448 canister to the fuel rail using an adapter fitting, then running OTC Inject-R clean fuel injector cleaner through the fuel rail with the engine running. The procedure was done as outlined in the OTC manual, and the guidelines vary depending on the manufacturer and model.

This demonstration is published in good faith as entertainment, but it is NOT a qualified instructional video. Obviously even a minor error while doing this procedure could have life threatening consequences, with serious risks of fire and vehicle and building damage. So, if you feel you need to clean your fuel injectors, it is highly advisable that you consult a professional. Do not try this at home.
