Carb not getting Fuel

Alright, I am having a major issue. The carb is not getting fuel at all. The carb and the fuel pump are only a day old, yet the pump is not supplying fuel to the carb. The fuel lines are all solid, with no holes or anything. We have a manual pump on it right now, but we are installing an electric fuel pump. Before we go through that stage: Is there anything that could be wrong other than the manual fuel pump not being powerful enough (3 pound pull), or being bad altogether? I fell for the ol' '74 seatbelt interlock dilemma, so is there some unknown force working against us that we don't know about?

Thanks for any help.
