40083 NOS Fuel Pump; what's it worth?

[Lynn]

I would have purchased this in either the late 70s, or around 1996 or around 2001. Went on a few buying sprees using the old Chevy High Performance Catalogue. I cannot find any date on the box. Pump has an aluminum tag that reads "AC 40083" and below that: "469" I think.

AC is NOT embossed on the pump anywhere that I can see.

I do not believe this is assembly line correct. It is an over the counter HP pump.

My camera is down at the shop. Headed that way in a little bit. Will post pics when I get back.

Need some informed opinions.

Thanks for any help.
