The Ford 6.7L engine was outfitted with a completely new type of common rail system from the lift pump, high pressure fuel pump, injectors and fuel filters. What we have discovered (and so have many others at their expense) is that the fuel system components are very sensitive to water and debris, much more so than previous fuel system designs. The Dieselsite 2011-2016 Ford 6.7l Fuel Filter/Water Separator protects your fuel system from being damaged by water and debris.
