XDP CAT Fuel Filter Adapter with Filter, Bleeder Screw, and Spacer 01-16 6.6L GM Duramax

The best upgrade you can make to ensure the longevity of your Duramax is to add additional fuel filtration. Its been proven time and again the stock filtration allows excessive material to pass onto the injectors, quite literally destroying them. This complete fuel system upgrade gives you proper filtration with nothing else left to be desired.

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.
