Injector Tool Instructions：
If the tool is experiencing extreme tension, something is seizing the injector inside the head. If you force the injector with enough pressure to break the tool or bend the tension bolt, you stand a good chance of damaging the injector itself, causing a need to remove the head. That can cost hundreds of dollars in labor alone.
Please soak injectors repeatedly everyday with some kind of solvent like PB Blaster. If you experience extreme tension on the tool, you can try it on some other injectors to see if they come out easily. Usually only a few will be stuck, causing you to either bend the bolt or break the injector pieces where the injector holding bracket would be if installed. Also it will help if you grease the allen screw where it meets the tension bolt inside the tool after several uses.
