I haven't built a Q-jet in a long time, but the last kit I used was from Tomco. It was really good, but I don't know if they exist anymore. There was a thread on another forum about a year ago about difficulies finding good accelerator pumps, so maybe that has resolved. If it was me, I would see if you can get a kit from GM first, if not I would buy one at NAPA.
