This Drop-in Series Fuel System protects your L5P Duramax from the problems caused by contaminated fuel.
Without proper fuel filtration, modern diesel injection systems are susceptible to excessive wear, which can cost thousands of dollars! By removing 99% or more of the water from your diesel, as well as entrained air and debris down to 2 microns, the Drop-In Series System protects the L5P injection system from premature failure.
Furthermore, by removing the aforementioned contaminants, Fass’s Drop-In Series System for the L5P Duramax optimizes fuel economy (results vary), restores power, and refines throttle response.
Fass’s industry-leading water decontamination capabilities (exceeding 99% by third parties, have been confirmed by Fass’s unique Extreme Water Separator (XWS) design. Should the Fass XWS reach capacity, it acts as a dam, shutting down your truck and preventing major destruction of fuel system components.
