DEF in the fuel tank, water contamination, or a failed CP4 can all create the same ugly problem: contamination throughout the 6.7 fuel system, leading to further parts failures.Simply flushing the system can leave contamination behind, which can lead to repeat parts failures after an already expensive repair. 

Doing the complete kit is more work up front, but a much better plan than paying for the same repair twice. Our Fuel Contamination Kits put the major replacement components together in one package so you are not chasing rails, injectors, lines, and a pump one piece at a time.
