Protect your fuel system with superior filtration. Built right here in-house, we are happy to offer this high-quality machined CAT fuel filter adapter for your 2001-2016 Duramax This adapter replaces the restrictive factory filter setup on your truck with a CNC-machined, billet aluminum housing designed to accept 2-micron CAT filters.

By switching to a CAT filter, such as the popular 1R-0750, you gain access to high-efficiency filtration that is readily available at a much lower cost than OEM units. Our unique central adapter design eliminates the leak path through the threads that is common on other inferior adapters. This kit ensures you keep clean, high-pressure fuel feeding your powerhouse while making routine maintenance faster and more affordable.

WIF Sensor: This installation requires the removal of the factory Water-In-Fuel sensor. No CEL codes will be triggered.
