My '79 doesn't have an air pump. I'm not complaining, the car has past the smog test here in California twice since I bought it in March '02. My question is " are the cars that were sold in California the only ones equipped with air injection pumps"? Just curious.

 

I don't think so. My '77 L-82 has the original air injection pump and has always been in Texas.

 

Nope, pretty much all C3's had em - even the L88.

 

Here is a listing that was posted on the NCRS Forum by Joe Lucia....

1966 CA-delivered Corvettes, except for the L-72, used the A.I.R. (RPO K-19) system

1967 CA-delivered Corvettes, used the A.I.R. (RPO K-19) system.

1968 & 1969, ALL Corvettes used the A.I.R. system regardless of engine, transmission, or where delivered.

1970, Chevrolet went to the CCS (Controlled Combustion System) for emissions control on most Corvettes, except the LT-1s.

1971, Corvettes continued to use CCS (except LT-1s and LS-6s).

1972, A.I.R. system returned for most Corvettes except engines except L48s with the "CKW" and "CKX" code.

1973 - 1975, all Corvettes used A.I.R, except for the 1974 L48 with automatic and Federal emissions which used CCS.

1976, all Corvettes returned to CCS, except California-certified cars which used A.I.R.

1977, all Corvettes used CCS, except California and "High Altitude" delivered cars which used A.I.R.

1978 & 1979 all Corvettes used CCS, except California cars, "high altitude" and all L-82s which used A.I.R. L-82s were not available in California or "high altitude" areas during these years.

1980 - 1987, all Corvettes used A.I.R.

1988 - on, A.I.R. was used on most, if not all Corvettes, although many C4s use an electric air pump.

 

Thanks Tom, guess I have a non Calif L-48 car. I like not having that air pump and belt under the hood. There's already enough hoses and belts. Thanks again!
