ALLIANT POWER L5P FUEL CONTAMINATION KIT AP54822 | 2020-2023 6.6L Duramax L5P

Restore your fuel system after contamination with the Alliant Power AP54822 Fuel Contamination Kit. Designed as a comprehensive OE-style replacement solution, this kit includes the critical components needed to repair a contaminated fuel system caused by metallic debris, water intrusion, DEF contamination, or microbial growth.

Replacing every affected component is essential when repairing a contaminated common-rail fuel system. Residual debris trapped in reused components can quickly damage new injectors and pumps, resulting in costly repeat failures. The AP54822 kit provides a complete repair solution using components assembled in an ISO 9001:2015-certified facility and 100% end-of-line tested at multiple inspection points to ensure leak-free operation and reliable performance.
