Description
Fuel Rail Pressure Regulator for 2024-2026 6.6L Duramax
GM # 12731369
Genuine GM Fuel Rail Pressure Regulator / Fuel Pressure Relief Valve for the driver (left) side rail. This original equipment part is specifically designed for the 2024+ L5P and L5D Duramax engines. Over time, worn or failing regulators can cause fluctuating rail pressures, hard cold starts, erratic idling, throttle lag, or active trouble codes. Sold as an individual service part, this allows you to replace a faulty regulator directly on the fuel rail without the unnecessary expense of buying a completely new rail assembly.
Features:
- Direct Replacement Part – Ensures Exact Fitment
- Restores drivability issues caused by inconsistent rail pressures
- Cost effective service part – Replace the faulty regulator without having to replace the entire rail assembly
- Acts as fuel pressure regulator and pressure relief valve
