Description
Description
Restore proper fuel system performance with this OEM GM high-pressure fuel rail assembly, engineered specifically for the updated LZ0 Duramax platform. This complete assembly includes both the factory-installed fuel pressure sensor and high-pressure relief valve, making it the ideal replacement when repairing fuel contamination, pressure issues, or injection pump failures.
If your CP4 or high-pressure fuel system has suffered contamination, replacing the fuel rail is strongly recommended to prevent debris from re-entering the system and causing recurring injector or pump damage.
Built to GM’s strict OEM standards, this direct-fit assembly ensures proper fuel pressure regulation, injector operation, and long-term reliability. Replaces 40009114
