Z482 injection pump HELP!!

[ARGO]

I have a 2 cyl SNO YL7663 in a generator . NOBODY recognizes the numbers and Kubota hangs up.
I need parts internally from a Zexel (Bosch) injection pump, specifically springs. I can pull up a blowup, but no part # list attached. The blowup shows part # 50. I'd be grateful for any help, especially a part source for these. Id buy a whole pump as a last resort, or a core. Apparently the 3 cyl uses the same barrels etc.

I'd send the pump to the place @North Idaho Wolfman recommends, in Oregon. He'll be on here to tell you

On the flat spot facing up right next to the injection pump what is the number stamped in it?
And what is the cast number (cc) on the right side of the block?
Is there a tag on the injection pump?
