This system outperforms stock pumps and competing options by separating 100% of air and up to 92% of water from the fuel before it reaches the injectors, ensuring steady pressure even under heavy loads or high-horsepower demands exceeding 1000 HP. Drivers report noticeable gains in throttle response, reduced injector wear, and fewer fuel-related issues compared to factory setups or basic filtration kits, making it the reliable pick for daily towing, racing, or tuned performance trucks.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eExact Vehicle Fitment\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eYears\u003c\/b\u003e: 2011-2014\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eMakes and Models\u003c\/b\u003e: Chevrolet Silverado 2500HD, 3500HD; GMC Sierra 2500HD, 3500HD\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eEngine\u003c\/b\u003e: 6.6L Duramax LML Diesel (Cab \u0026amp; Chassis models included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eNotes\u003c\/b\u003e: Direct bolt-on installation using factory frame standoff, no modifications to the CP4 high-pressure pump required.
