Pump identification

[megastang]

So I've been going through some of the parts we've accumulated over the years and I'm thinking it might be about time to build a pickup. Could someone give me information on this pump 0 402 066 709. Thanks!

There should be a number starting with "PES6P...."

Post that one and we can decode it better.

Hmm, I tried to use caps for the letters but it changes to lower case automatically

Cummins number 3991337?
Still chasing, but narrowed it down to possibly being a 173HP P-3000.
