On our cars which may be subject to vapor-lock ('41 Caddy with the carb right ahead of the exhaust manifold crossover pipe) the electric pump can be switched-on to push the fuel through to keep us running - even in slow/hot-running conditions.
I think that electric pumps should be ADDED, but not replace your original.
Also, remember that your mechanical pump is a puller (or sucker), but electric pumps are a "Pusher". Therefore the electric pump should be mounted as low and as close to the tank as possible, preferably grounded directly to the frame (depending upon your car's polarity - of course).
The electric pump should have a cut-off switch in easy reach of the driver, and be fused independent of the ignition circuit. When your engine cuts out the mechanical pump also quits, BUT AN ELECTRIC PUMP COULD KEEP PUSHING FUEL, EVEN IN AN EMERGENCY SITUATION, potentially feeding a fire.
The eletric pump can get you back home even if the mechanical pump fails - also if the mechanical pump diaphram were to fail and push gas into the oil, a simple bypass of the mechanical pump can still save your engine -- I've been there!
I've seen some hair-brained wiring set-ups (even done some in my early days) that would invite disaster under the right(wrong?) conditions - you know - just to try it out for now, and several years later a bum connection results in a garage fire or worse.
Go ahead and have a backup system if the car is a driver, but do it safely and enjoy your rolling piece of AMERICANA.
