Just make sure you avoid the real high pressure EFI type pumps, they will cause all sorts of problems with a carb (such as large quantities of uncontained fuel and fires). The other thing to be wary about with electric pumps is that unlike a mechanical pump, or a modern EFI pump hooked up to an appropriate computer, they do not stop pumping in the event that the engine stops. This is particularly dangerous in the event of a crash or fuel leak, as fuel will continue to flow until the ignition is turned off.
There are a number of products available that will cut off fuel pumps in the event of an accident.
