Restore, upgrade, or completely overhaul your fuel filter head with the Merchant Automotive Fuel Filter Head Rebuild Kit for 2001–2010 GM 6.6L Duramax trucks.
Choose from three kit options: Seal Kit, Deluxe Kit, or Master Kit, to match your needs, when you're doing routine maintenance or a full refresh.
- The Seal Kit includes everything needed to stop pesky fuel leaks and keep your filter head functioning like new, featuring all the essential seals and O-rings.
- Step up to the Deluxe Kit and you'll get the full seal set plus the Merchant Automotive aluminum bleeder screw and Water-In-Fuel (WIF) sensor delete plug, replacing the problematic factory plastic components with durable, precision machined aluminum for long term reliability.
- For the most complete solution, the Master Kit includes all of the above along with an OEM ACDelco fuel filter and a 16oz bottle of Merchant Automotive Diesel Fuel Treatment, perfect for those who want a comprehensive refresh and better filtration performance.
Wondering about deleting the factory WIF sensor? The OE plastic sensor has a history of being inaccurate, brittle, and prone to damage during filter changes. Merchant Automotive’s aluminum delete plug eliminates those issues without triggering any warning lights or affecting your truck’s warranty. Just be sure to use a metal-body filter like the ACDelco for proper fitment, as some plastic filters may not seal correctly with the rigid aluminum threads.
Whether you're just fixing a leak or going for a full-on upgrade, this rebuild kit lineup gives you reliable options to get your Duramax fuel system running clean and strong again.
