Overview

This Dieselsite Fuel Filter & Water Separator is designed for 2011-2016 Ford 6.7L Powerstroke engines, and explicitly does NOT fit 2017 and newer models. It addresses the sensitivity of common rail fuel systems to water and debris in ultra-low sulfur fuel, which can lead to catastrophic failure and costly repairs not covered by warranty if rust is present. The system installs in under 15 minutes without cutting or modifying factory fuel lines, using OEM-style quick connects. It comes with two spare filters. The filter works by first passing fuel through a separator cone to remove water and large particles, then through a 2-micron particle separator. It installs in series before the primary filter, protecting all OEM fuel system components without restricting fuel flow.
