Something is wrong if you're having to prime the carb everytime you start your car. The carb should have gas in the fuel bowl without needing the pump to fill it each time. I can let my car sit for a month or more, and it fires right up with no choke, my setup is just a Carter street pump feeding a Holley double pumper. The question you should be asking is why is my carburetor empty and where is the fuel thats supposed to be in it going?
My 2-cents says you've got other problems. I wouldn't be suprised if you're dealing with a flooding issue, not lack of fuel (??).

It will work fine but you do not have to run parallel lines. I have a Holley electric back by the tank and it pushes through the mechanical just fine. I have both a manual switch under the dash for priming and the like and a micro switch that is actuated by the secondaries on the carb. That way, I don't have to listen to the electric pump all the time, but have the flow when I need it. This system has fed the Dominator on the street and track for years now.
Master, again and still

I looked at doing this and using a 5 second relay: ignition on, 5 seconds of priming, pump off, start engine, ignition off, ignition on, 5 seconds of priming, pump off, start engine...but the relays are 40 dollars each. Tim

I have found using a stock enclosed air filter housing has slowed the evaporation of the fuel in my carb verses a open air, air filter.
What does this mean? Open vs. closed?

I'm thinking he is referring to a snorkel type air filter as being "closed" and a K&N style as being "open".
