3 cylinder fuel pump info

[JMBT]

Well I finished my 2 cylinder pump upgrade and the truck is running great! I took the head off the old 3 cylinder tonight an was amazed to see at nearly 600K it was perfect inside! The cylinder bores, tappets, rollers, springs, and cam didn't show ANY signs of wear, and the ceramic plungers looked brand new except a small line on the bottom of one. Everything I inspected would have passed Cummins reuse criteria in the service manual. I will try to post some pics of the internal parts when I get a chance.
Talking to the Cummins shop here when I was ordering the parts, the service guy told me that my truck being an early 11 model CM 2250 it never had a recall campaign on the pump. He said the only campaign mine would have been included in was only to repair the damage after the pump failed, if it happened before 500K, but no actual "recall" like on the newer ones. So I am confused, were all the ceramic plunger pumps bad or not?? If so why not recall them all? Or even better make a steel upgrade for the 3 cylinder to save guys some money! C'mon Cummins, you can do better, WTF! I feel like big red is jerking me around here!
