The Motorcraft PU7Z-9C968-B is the injector pressure regulator for a late 7.3 Powerstroke. It is the valve, not the seal kit. Motorcraft CM-5013. It supersedes F81Z-9C968-AB.

The IPR is what the PCM uses to build and hold ICP. A sticking valve or a screen packed with metal is a hard start, a no-start, and a truck that will not stay running. This is the late-style valve, for engines serial 187100 and higher, which is the 1996–2003 range. Do not order it by year alone on an early truck. A 1994–1995 pump uses a different regulator. The seal kit is 4C3Z-9C977-AA if the valve itself is still good.

It fits 1996–2003 F-Series, E-Series, and Excursion 7.3 trucks with that serial. The Alliant match is AP63402.

Fitment

• 1996–2003 Ford 7.3L Powerstroke
• Engine serial 187100 and higher
• Genuine Motorcraft PU7Z-9C968-B
• Valve included
• Supersedes F81Z-9C968-AB
• Does not fit 1994–1995

Clean the bore before it goes in. Metal in the screen means the pump or a lifter is coming apart, and a new valve will fill up again.
