Dieselsite DSFF67 Fuel Filter and Water Separator SystemThe Ford 6.7L engine was outfitted with a completely new type of common rail system from the lift pump, hp fuel pump, injectors and fuel filters. What we have discovered (and so have many other at their expense) is that the fuel system components are very sensitive to water and debris, much more so than previous fuel system designs. A known issue thats surfaced with the 6.7L Power Stroke is the ability for water to pass through the factory fuel filter, potentially causing thousands of dollars worth of damage. DieselSites new fuel filter/water separator system prevents water and particulates from entering the fuel system on your 11 to 13 Ford Super Duty and filters particles down to 2 microns. Systems come complete with billet-aluminum, machined quick-connect fittings, stainless steel lines, and fuel filter minder. Kits fit any cab configuration and require no cutting of hoses or drilling of the frame.
