I just put a used Holley on my 1882 CJ7 -AMC 258 i6 / 4.2l
Everything seems to be working fine other than a little bit of gas leaking out of the accelerator pump/housing. I've been looking since yesterday afternoon and can't figure out how to determine wheather it has a 30cc or 50cc pump.
The stamped number on the carb is 4412-3 which equates to a model 2300 500cfm

Just wondering is someone on here can tell me which accelerator pump diaphragm to get? And also maybe you can tell me how to retrieve said information so I will know how to look up individual parts for future maintenance if/when needed?

Or are the diaphragms the same and the difference is in the spring and cam?
