7.3L Powerstroke Alliant Power IPR Valve (1994–2003)OEM-Quality Replacement Injection Pressure Regulator Valve This Alliant Power IPR (Injection Pressure Regulator) Valve is a direct replacement for the factory unit found on 1994–2003 7.3L Powerstroke engines. Mounted in the valley on the High Pressure Oil Pump (HPOP), the IPR valve plays a critical role in regulating oil pressure to the injectors—essential for proper engine performance. Common signs of IPR valve failure include hard starts, stalling, poor throttle response, or no-start conditions. These issues often result from sticking components, damaged seals, failed sensors, or frayed wiring. Before replacing: Inspect wiring and connectors for damage Ensure the tin nut on the back of the IPR sensor is secure Check for oil leaks or debris around the valve Installation Notes: Torque the IPR valve to 35 ft/lbs Do not use thread sealer – the valve has a built-in orifice in the threads that must remain unobstructed Fitmen
