The only problem, IMO, with running the electric thru the mechanical, is in the event the diaphram ruptures in the mechanical, the electric will continue to pump and fill the engine block with fuel in a matter of minutes. It doesn't happen very often, but it is just a thin piece of rubber. It is nice though to have the backup in case of the electric failing. In my 496 KC, I'm running the Aeromotive 11203 pump with a 13301 regulator set at 7 psi with a return line (3/8' SS and -8 an where needed). So far no problem with fuel delivery, but I haven't really pulled it very hard yet. There is a pic of the setup in my gallery if interested.
