XDP Duramax CAT Adapter with 1R-0750, Bleeder Screw & Spacer;

The XDP Duramax CAT Adapter with 1R-0750 Filter, Bleeder Screw & Spacer is an easy way to upgrade the fuel filter on your 2001-2015 GM 6.6L Duramax. The durable anodized filter adapter simply threads on to the OEM Filter Head and allows you run the more efficient and less expensive CAT Filter on your truck. For an even easier filter change, we also include a filter head spacer to give you more clearance for filter changes, along with an aluminum bleeder screw to replace the factory supplied plastic version that is commonly damaged during routine maintenance.
