Description

The Alliant Power AP54822 is a remanufactured fuel contamination kit designed for 2020-2023 Chevrolet and General Motors vehicles equipped with a 6.6L L5P engine.

This kit is intended to address issues such as P0087 (Fuel Rail Pressure Low) codes, inadequate fuel pump lubrication due to low fuel supply, potential pump failure, or accidental Diesel Exhaust Fluid (DEF) contamination. Failing to replace all affected components risks further damage to new or remanufactured fuel parts. The kit includes remanufactured common rail injectors and a common rail pump, along with various gaskets and seals to ensure a complete fuel system replacement.
