Overview

The XDP XD171 Cat Adapter Filter Kit is a fuel filtration upgrade designed for 2001-2016 Duramax models. This kit allows you to use the more efficient and less expensive CAT 1R-0750 filter with your factory fuel filter head.

It includes an anodized aluminum filter adapter, a fuel filter head spacer for easier filter changes, and an aluminum bleeder screw to replace the often fragile plastic factory version. The installation requires no modifications to your existing fuel system.
Show original supplier description
The XDP XD171 Cat Adapter Filter Kit provides an affordable and effective way to enhance the fuel filtration system on your 2001-2016 GM 6.6L Duramax. This kit's primary feature is the durable anodized aluminum adapter that threads directly onto your OEM fuel filter head. This allows you to run the highly efficient and cost-effective CAT 1R-0750 filter, which can significantly reduce long-term filter replacement expenses while improving fuel quality and protecting your engine from contaminants. A key component is the included fuel filter head spacer, which creates additional clearance, simplifying the process of filter changes. Additionally, the kit replaces the factory plastic bleeder screw with a more robust aluminum version, which is less prone to damage during routine maintenance. This adapter filter kit integrates seamlessly with your existing fuel system, requiring no modifications. However, please note that this product does not ship to California and is not CARB compliant.
