Cummins 177761 RC 3 PM Injector Pump 139668 0 NHC-250 153338 69896530 BM70486

Description

I GOT THIS FROM A FUEL SHOP THAT DID A LOT OF PUMPS AND INJECTORS.
IT WAS IN THE CASE WITH THE LABEL "CUMMINS MASTER PUMP", PLEASE SEE LAST PIC.
TOP IS STAMPED BY THEM, 6989965, 30
I WOULD IMAGINE IT WAS USED FOR TESTING/SETUP, ETC.
SPINS VERY FREELY, MAY BE A USABLE PUMP, BUT ASSUME NEEDS PERHAPS SOME PARTS/WORK??
THANKS FOR LOOKING!
