    Need identifying numbers for a '66 smog pump.

    For a SB. The AIM only provides the "part" number. Also could use digital images or a description of same if anyone has them. Did any other GM applications use the same pump? Did '66 differ from '67?

    Any assistance would be greatly appreciated.

    The 66 and 67 Corvette AIR pumps were unique-to-Corvette pieces. They can be identified by the fact that the air outlets were from a "T"-like fitting which attached to the bottom of the pump's aluminum housing. All other 1966-67 AIR pumps had outlets which emanated from the cast iron, rear plate of the pump. Some Corvette pumps have unmachined bosses on the rear plate which would otherwise have been machined out for other applications. Other Corvette pumps have soft plugs installed in the outlet holes used for other applications.

    After 1967, no AIR pumps that I am aware of used outlet fittings which were taken off the bottom of the main aluminum body of the pump. So, if you find a pump with the "T"-like fitting on the bottom of the housing and no functional outlets on the rear plate, then you've found a 1966-67 Corvette pump.

    The 1966 and 1967 pumps had different part numbers and were in some way different. However, I don't know what the difference was. Functionally, they are interchangeable and, I believe, the 1967 pump replaced the 1966 pump for SERVICE. Mostly for the latter reason, the 66 pump is, by far, the more difficult to locate.
