You'll be surprised at how small of a fuel pump
you really need. It's all based on how much power you
expect to make, regardless of engine size, carb type,
cam specs, etc. A naturally aspirated motor only needs
..4 to .5 lb/hp/hr.

to the Aeromotive web site for an excellent tutorial
on selecting a fuel pump.

IMO, electric is clearly the best racing pump.
But for a fun street car, it's too expensive and too
complicated. A mechanical pump will work just as well
on the street for a third of the cost and a lot less
work to install properly.
