Description
Restore proper fuel system control with this Genuine General Motors Fuel Pressure Regulator, part number 55495697, designed for 2017–2023 GM Silverado & Sierra 2500HD/3500HD trucks equipped with the L5P Duramax diesel.
This regulator is mounted on the HP4 high-pressure fuel injection pump and is also commonly referred to as the Fuel Injection Pump Metering Valve.
A failing fuel pressure regulator is a common cause of surging, loping idle, fuel pressure loss, and drivability issues on higher-mileage Duramax engines. Replacing it with a genuine GM unit restores precise fuel metering and stable rail pressure.
This is the highest quality OEM replacement available — not an aftermarket knockoff.
