Date code on A.I.R. pump....
and diverter valve. Have someone interested in my smog pump but need to know what year this thing is. If anyone could help it would be greatly appreciated.
pump--#7801149 (perhaps a 96 after) and D 15
div. valve--#DS17084025/30501
Thanks, Randy

GM #7801149 was used on Corvettes from 1970 through 77. The date code is stamped on a machined surface that serves as a bolt boss and on the vehicle can only be viewed with a mirror. the 7801149 pump used a Julian date code in the format of 06042 where 060 is the day of the year (60th), with year (4) and shift (2). So this is a March 1st, 1974.

FYI - the "149" pump casting was used on MANY vehicles and they are not all machined the same way. Buick pumps use the same casting but the pump will not bolt on to a Chevy.
That one on ebay looks like a typical Chevy Camaro/Nova/Chevelle etc. setup that attaches down near the bottom close to the fuel pump.
