ALLIANT POWER AP63417 INJECTION PRESSURE REGULATOR (IPR) VALVE

The Alliant Power AP63417 Injection Pressure Regulator (IPR) valve is designed for Ford® and International® diesel engines equipped with HEUI fuel injection systems.

The IPR valve controls high-pressure oil flow to the injectors, helping maintain proper injection pressure, fuel delivery timing, throttle response, and engine operation. A failing IPR valve can lead to hard starts, stalling, rough idle, injector performance issues, low ICP pressure, or no-start conditions.

Built as a direct-fit replacement, the AP63417 features durable construction and includes a mounting gasket for easier installation during fuel system or high-pressure oil system service.
