Keep your 2001–2004 GM 6.6L LB7 Duramax diesel engine running strong with high-quality fuel system parts and additives from Norcal Diesel Performance. The LB7 Duramax is known for its smooth power and efficiency, but like any common-rail diesel, it relies on clean fuel and proper lubrication to protect injectors, pumps, and internal components. Our selection of LB7 fuel system parts includes trusted solutions like Justice Brothers Diesel Fuel Supplement, Diesel Power Plus Fuel Additive, diesel fuel antigel, and oil system cleaners designed to improve fuel lubricity, clean injectors, reduce deposits, and prevent cold-weather gelling.
