2011-2014.5 Powerstroke 6.7L Fuel Contamination Kit (6.7-CONKIT)

Water and solid debris are the two main causes of contamination in the diesel fuel system. Once contaminates are introduced into the fuel they become trapped in the system causing damage as they circulate through. 

The best way to ensure that the contaminates are removed from the fuel system is by replacing the main fuel system components where the debris has become trapped.
