It actually followed the injector, we have been careful with installation and adjusting them. Truck has been sitting for about year and a half. I will check fuel quality to make sure injectors are not getting contaminated from the fuel. I guess I will get 3 more cummings injectors and see if they will warranty the one. I will drain tanks and start with fresh fuel to be on the safe side.

A 10-micron filter in the davco unit helps tremendously towards keeping injector and the fuel system clean.
