    Maintaining the integrity of a high-pressure common rail fuel system is critical for the longevity of your 2013-2018 Ram 4500 or 5500. Whether your 6.7L Cummins has suffered from Diesel Exhaust Fluid (DEF) ingress, water contamination, or general component wear, the consequences of a compromised fuel system can be catastrophic to your engine's internal health. The Alliant AP57021 Fuel Contamination Kit offers a comprehensive, professional-grade solution designed to restore your vehicle to factory specifications. By utilizing components from industry leaders such as Bosch and Cummins, this kit eliminates the guesswork and reliability concerns associated with aftermarket alternatives, ensuring your cab and chassis model remains a dependable asset on the job site.

    • Uncompromising Quality Control: Every critical component within this kit undergoes rigorous end-of-line testing at 15 distinct pressure and flow points to guarantee zero leakage and precise performance.
    • Comprehensive Restoration: This all-in-one package provides every necessary component for a complete fuel system overhaul, reducing downtime and ensuring no contaminated parts are left to compromise the new assembly.
    • OE Validated Reliability: To maintain the high standards of your 6.7L Cummins engine, the kit features 100% genuine OE or OE-equivalent components, providing a seamless fit and factory-level operation.
    • Certified Domestic Craftsmanship: Each kit is proudly assembled in the United States within an ISO 9001:2015 certified facility, adhering to the strictest international quality management standards.
