The Freedom Filters CAT Adapter with Fuel Filter, Bleeder Screw & Spacer is an easy way to upgrade the fuel filter on your 2001-2016 GM 6.6L Duramax. The durable anodized filter adapter simply threads on to the OEM Filter Head and allows you run the efficient and inexpensive CAT Fuel 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. This product features a one year warranty.
