The GM #7817575 AIR pump was used only for the 1975 model year. It is configured identically to the GM #7803948 pump used for all 1969-74 Corvettes. So, what's the difference between the two pumps? I wish I knew.
Attached are photos of an NOS example of the 7817575. This pump was manufactured on the 225th day of 1974 (August 13).
It's NOT for sale.
