It would be the third series of AC pump introduced to the M38A1. It was common for AC to only place the last four digits of the AC part number on the flange of the pump. You'll find that pump listed in the M38A1 ORD 9 SNL G-758 dated SEP 1956 on page 83.

Yes, under "Downloads" click on "M38, M38A1: Drivetrain" then click on "Engine".

The Fuel Pump Manual is under "Main/M38, M38A1, M170, M606" and is not in a sub-file.
