Review on 🔧 OxGord Fuel Injector Puller Tool for Chevrolet C4500 Kodiak, Silverado 2500, Silverado 3500, C5500, Sierra 3500 with Duramax 6.6L Diesel Engine - Enhanced Fuel Injector Puller by Petr Webster

It took some work but the old injectors were removed. DON'T COUNT YOU WILL REMOVE THE JETS! (If you do, it will break, as the bad reviews suggest.) It requires skill. I turned the jets all the way down, sprayed some lube in the cups, and used a wrench rather than a ratchet. Keep moving the tool/injector back and forth. Most will burst instantly, but even stubborn atomizers will eventually detach.
