The Southern Plains Cummins parts guy just called to say the square cut o-ring that was supposed to be overnighted to me is unavailable, but he will work on getting me one. In the meantime I am stuck. Does anyone have a o-ring Cummins #3923194? A picture of it is here, post #19 http://www.turbodieselregister.com/f...failure-2.html

To make matters worse the truck is up on ramps parked in front of the boat garage door, so I can't even go fishing:{

Any help is appreciated.

Gary
