GMC Sierra 6.6L Duramax Fuel Filter Delete

For off-road competition use. This kit replaces the factory plastic fuel filter housing which is prone to cracking and leaking. The billet aluminum adapter block allows you to run a standard spin-on fuel filter (like a CAT filter) which offers finer filtration (2 micron) and is significantly cheaper to replace than the OEM cartridge. Includes the billet head, mounting bracket, and one high-efficiency filter. Ensures clean fuel reaches your high-pressure injection pump (CP4), prolonging its life.
