Genuine OEM GM 55495697 HP4 Fuel Pressure Regulator 2017–2023 L5P Duramax Diesel
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.
