Thumbnail Filmstrip of 1996-2003 7.3L Powerstroke IPR Valve Alliant AP63402 Images
The Alliant AP63402 is the injector pressure regulator for a 1996–2003 7.3 Powerstroke. It is the valve, not the seal kit. It is the version without the edge filter, and it replaces Ford F81Z-9C968-AA and F81Z-9C968-AB. The Motorcraft match is PU7Z-9C968-B. The warranty is 24 months, unlimited miles.
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. A 1994–1995 pump with the edge filter uses a different regulator. The seal kit is Ford 4C3Z-9C977-AA if the valve itself is still good. The FFD229 wrench is what gets it out without pulling the pump.
It fits 1996–2003 F-Series, E-Series, and Excursion 7.3 trucks, plus the matching T444E.

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.

Worked great. Always tried to buy Motorcraft but leary with rumors of supplier changes.

So I spent 200 on a new IPR. When it arrived the packaging was ripped half open and part of the IPR was sticking out. The box’s outer flap was completely ripped off and missing…. No where in the packaging, not sure how that happened. Overall the part worked as it should but we will see how long it last due to it being opened and banging around.
Reason for the 3 star is due to packaging. A 200+ dollar part shouldn’t come with opened plastic and a ripped box.
Note From Store Owner: We appologize for the shipment damage. Most of the issues are from the shipper and sould not affect the prerformance of your product.

Bought Alliant IPR valve and so far on my 2000 7.3 ifs working great, it fixed some of the issues that I wasn’t going after but it fixed those issues, now I am ordering a ICP sensor hoping to fix the issues I’m still having! GREAT PRODUCT!

I ordered an IPR and then an ICP from another company to address a very long crank problem that progressed quickly to only starting with the icp unplugged. Everything I order from FFD gets to me in less than 2 days from ordering and I got a chance to put it in yesterday. Immediately solved the long crank issue and the truck runs much better than it did before. The icp came in while I was replacing the IPR and now it’s going to sit in the glovebox since the IPR was my issue. The truck ran very rough after replacement while it got the air out of the HP oil system and after that it was smooth sailing.

First order from Full Force and I�m very happy. The ordering process was very smooth and easy. I only ordered the IPR as a backup for my 99.5 F250. I�m sure I will need it eventually though. Thank you Full Force staff and I�ll be ordering more from you as needed.
