I went to one of storage unit auctions today. I landed up buying a nice unit full of all kins of autoparts and tools. Anyway, while i was looking through some of the boxes and i found a few cummins injectors. Some look old some look new. My problems is i cant figure out what they are from. They are remanufactured, but dont what year series or anything. Any help would be greatly appreciated.

The part number is 3802677-RX

 

i'm going with a 2nd gen injector from appearances.
