Identify smog pump and diverter?

[TDW]

A friend is cleaning out his garage and found 3 of these pumps. Anyone know what they came off of?

Cast number on rear plate of pump....7801149
cast number on diverter....7024241
date....16021R
pulley....1238316

Thanks.

The 149 Casting date is correct for that piece of the pump and held true for many years......but still ALL pumps aluminum bodies are not the same.

I believe the date would be the 160th day, 1972, 1st shift at "R" manufacturer ....................

316 pully would be standard NOT deep groove

I do not know 241 divertor application.
