will a radical cam affect a fuel pump?

if so would i be better off with a high performance fuel pump or an electric one?

I don't know why it would be. The pump is driven based on RPM's. Now if the cam increases the horsepower significantly, such that the other can't keep up, then maybe a change is in order, but this would mean you probably are running high flow heads, a large carb all the other go really fast goodies too.

i think only if you are pulling to much HP for the pump to keep up with so i doubt it.
