the kit with the plungers, tappets, and barrels fits both the 3 and 2 cyl pump. i dont know why cummins has such a hard time with this!! I still see 3 cyl pumps fail with updated parts though, so fair warning on that.

I found video at quickserve saying 60ft lbs and 60 degrees.

Also barrels and plungers for 2250 and 2350 have different part number and they cannot be mixed. Installing incorrect barrels and plungers will result excess fuel in the oil

They have different part numbers:
