Not strictly speaking true...fuel pumps cross over to some first gens (and maybe other Chevy models). I’ll post a screen shot from a GM parts catalog of part numbers and applications later.
I was just comparing the part with ONLY 2nd gens, and especially between 70 and later Camaro's. With this I think I am correct. Basically, between 70 and 71-later I think 70 was the only year that had a vented tank so no return line from the pump, thus the unique to 70 fuel pump. The actual pump I had in mind, part number 40725 or 40726 was used in 69 and earlier Camaros, Chevelles and others so you are correct on this.
Some of the 70 Camaros use the 40777 fuel pump which is the tall one with 3 lines. This pump was new for 1970 and was used on many GM vehicles until 1988. The 40725 pump dates back to 1967 and was used on many vehicles until 1987. The 40726 pump shows up in my books as a 1970 only pump for Camaro, Chevelle, and full size cars with small block engines.
Correct. My point was the 40725 was "used on many vehicles until 1987" but NOT the Camaro, for sure after 70. Also true on the 40726. Can't find anywhere else it was used other than 1970. AC fuel pumps are kind of hard to nail down on actual usage. The 40725 has the same specs as the 40726 and are service level replacements, but I have not been able to definitively find out whether they were fitted on the line to Camaro's. Do you know for sure, Gary?
My book shows the 40725 pump as installed on 70-72 Camaro with 307. It didn't show up on Camaro again until 1981 when it was used on 267, 305, and 350.
Floor mounted gas pedal was avail on the 71 Z28.

Same for 71-72.
The fasten seat belt appeared on 72's after the first of the year.
