Edelbrock performer help

I just got my motor running and put a used Edelbrock 1407 750 on it. I am wondering about the accelerator pump, when I open the throttle there is no visable or audible squirt of fuel, it idles good, but wants to bog when I snap the throttle, I am assuming that the accelerator pump is not working. What I am wondering is:
1. does this sound like a bad accelerator pump?
2. Can I just replace the pump without an entire rebuild?
3. If I decide to rebuild the carb does the rebuild kit come with a new accelerator pump?

Thank you in advance for your help.
