I Found 7.3 PSD IPR O-Rings separately

[dieselboy427]

I have been working on HD, MD, and, LD diesels for a long while, and came across IPR O-rings for Powerstroke. Caterpillar and Navistar share components: IPR, Injector design, and other small parts. The IPR o-rings are almost impossible to get through ford and navistar but caterpillar sells each in its own little bag. The part numbers are as follows: 033-6028 O-ring 123-3132 Backup ring 033-6039 O-ring I've never replaced these on a Cat for leaking, only as a service item when doing high pressure oil line. These are faulty on the PSD more often than the IPR but are not serviceable with ford parts. NOW THEY ARE SERVICEABLE!!!

From when mine failed in 2003:

IPR O-Ring Kit:
(Ford) F6TZ-9C977-AN
(International) 1825806C92

International kit cost me $11.00 or so back then.

Impeccable timing gents. I've been looking for a way to get an IPR o-ring kit without having to give Ford $40.

Thanks for the info.
