1972 Chevy Smog pump white (opaque) fan
 

Nice original piece, needs rebuilt. Not sure of the application of the diverter valve, but lots of other pieces in this original set up that can be used. Hose clamps are dated 1/71. $200, might part out.

If not mistaken the diverter is Camaro -
The stamped part numbers and dates began in late 1973 model year.
I believe the date 27941 is 279th day of 1974 shift 1.

This set up looks like its never been apart, and the date on the pump is 14 day of 1972. The number stamped on the diverter face (27941) is the part number, never seen a diverter valve dated. Will listen to offers if some can use it.
