Just thought this information would come in handy to the very very very small minority of people with carby hondas that are actually contemplating on modding it.
I will keep updating this thread when I do more and more research.

Suitable pumps:
Walbro bellows pumps are time-tested, reliable units that offer exceptional versatility for carbureted applications. One model fits most domestic cars and trucks. A second number covers most imports.
Walbro bellows pumps provide reliable, positive fuel flow for easier starting and reduced vapor lock problems. They are easy to install, and come complete with installation instructions and mounting hardware.
High performance and adjustable pressure bellows pumps are also included in the Walbro lineup, to satisfy special application needs.
In addition to automotive applications, Walbro bellows pumps are used in a variety of fluid delivery systems in industrial, agricultural and other specialized fields.
