1R-0750 FUEL FILTER ALUMINUM HEAD FOR 2001-2016 DURAMAX 6.6L LB7-LML

iFJF part No.: FJ-1R-0750-AD20. Product Overview Upgraded billet aluminum fuel filter head designed as a direct replacement for the failure-prone OEM plastic filter housing on 2001-2016 Chevy Silverado and GMC Sierra HD trucks with the 6.6L Duramax (LB7, LLY, LBZ, LMM, LML). The factory plastic housing is notorious for cracking, warping, and stripping threads leading to fuel leaks, air ingestion, and no-start conditions. Our CNC-machined 6061-T6 aluminum head permanently solves these issues. Key Features Solid Billet Aluminum: CNC-machined from 6061-T6 aluminum eliminates cracking, warping, and thread stripping common with OEM plastic housings. Precision Threads: Rolled stainless steel insert threads no more stripped plastic threads preventing proper filter seating. Upgraded WIF Port: Machined Water-In-Fuel sensor port with stainless threads maintains factory warning system without OEM port cracking. Direct Bolt-On: Factory mounting points, exact OEM dimensions installs in 30-45 minutes with basic tools. Lifetime Durability: Permanent upgrade that will outlast the truck unlike OEM plastic housing that may fail repeatedly.
