Restore proper high-pressure oil control in your 7.3L Powerstroke Diesel with a Genuine Motorcraft Injector Pressure Regulator (IPR) Valve. The IPR valve is a critical component of the 7.3L HEUI injection system, controlling high-pressure engine oil supplied by the HPOP to the fuel injectors. When the IPR begins to fail, the engine may experience hard starting, rough idle, stalling, unstable ICP pressure, or a no-start condition.
This Motorcraft replacement is designed for the later 7.3L Powerstroke application and is the correct choice for engines using the late-style IPR valve. The current Red River listing identifies this part as Motorcraft CM-5013 / PU7Z-9C968-B and specifies fitment for engines with serial number 187,100 and higher. SWAG Performance Parts
For buyers searching older Ford numbers, F81Z-9C968-AB is a commonly referenced earlier Ford service number for the late-style 7.3L IPR application, while PU7Z-9C968-B is used as a later replacement/service number. Riffraff Diesel
Why the IPR Valve Matters
The 7.3L Powerstroke uses a HEUI — Hydraulically Actuated Electronically Controlled Unit Injector — fuel system. Instead of relying only on conventional fuel pressure to actuate the injectors, the system uses high-pressure engine oil generated by the HPOP.
The IPR valve regulates that high-pressure oil circuit. If the valve cannot properly control oil pressure, the injectors may not receive the hydraulic pressure they need to operate correctly. Diesel Hub

Common Symptoms of a Failing 7.3L IPR Valve
A faulty IPR valve can contribute to symptoms including:
- Hard starting
- Extended cranking
- Hot no-start condition
- Intermittent no-start
- Engine stalling
- Rough or unstable idle
- Low ICP pressure
- Excessively high IPR duty cycle
- Engine that starts and then dies
- Loss of power
- Unstable high-pressure oil system operation
These symptoms can also be caused by other high-pressure oil system faults, so proper diagnosis is recommended before replacing the valve.
Fitment / Application
Designed for later 7.3L Powerstroke Diesel engines using the late-style IPR valve.
Typical applications include:
- Ford F-250 7.3L Powerstroke Diesel
- Ford F-350 7.3L Powerstroke Diesel
- Ford F-450 Super Duty 7.3L Powerstroke Diesel
- Ford F-550 Super Duty 7.3L Powerstroke Diesel
- Ford Excursion 7.3L Powerstroke Diesel
- Ford Econoline / E-Series 7.3L Powerstroke Diesel
- Other Ford applications equipped with the compatible late-style 7.3L Powerstroke Diesel
The late-style IPR is generally associated with 1996-2003 7.3L Powerstroke applications, although engine serial number is the safer identifier because Ford used different IPR valves in earlier engines. DieselHub identifies the late valve for 1996-2003 engines, while the Red River listing specifically requires engine serial number 187,100 and higher. Diesel Hub
Important Fitment Note
Fits engine serial number 187,100 and higher.
Do not order by model year alone on early 7.3L applications. Verify the engine serial number and existing IPR configuration before ordering.
For engines below serial number 187,100, the earlier-style IPR valve is required.

Installation Notes
The IPR valve installs into the high-pressure oil pump assembly and is exposed to high-pressure engine oil. Before installation:
- Verify the engine serial number and correct valve application.
- Inspect the electrical connector and wiring for damage.
- Inspect the IPR sealing area.
- Make sure all sealing O-rings are correctly positioned.
- Keep the component and surrounding area clean during installation.
- Do not allow debris into the HPOP or high-pressure oil system.
If diagnosing a hard-start or no-start condition, it is good practice to monitor ICP pressure and IPR duty cycle with an appropriate scan tool before replacing parts.
