Enhance fuel filtration efficiency and serviceability in your 2007.5-2009 Dodge 6.7L Cummins with the XDP Cummins 6.7L CAT Filter Adapter XD391. The XDP Cat Filter Adapter features a CNC-machined, billet aluminum filter head that is designed to replace the stock filter assembly. The new filter head is designed to accept the CAT 1R-0750 advanced high efficiency fuel filter to provide your Cummins engine with superior filtration and protection. The XD391 features a bolt-on installation by mounting the new fuel filter head in place of the factory housing. Removing the factory housing helps reduce maintenance costs, while also eliminating common issues like cracking, leaks, or seizing with the plastic filter canister design. Each kit comes ready to install with filter head, CAT 1R-0750 fuel filter, fuel filter delete (for factory low-pressure lines) and the necessary hardware for installation.
