For years I ran an electric pump in the fuel line just outside of the tank, that ran to the mechanical pump on the motor without issues. The electric pump was wired to turn on with the ignition and turn off with the ignition. Turn on the key, listen for the electric pump to slow down (about 20 seconds), and start the car like it ran yesterday. Pretty much ended long starter cranking times. But, I wasn't feeding a dual quad 440 either.
mine can sit for a year, let the electric do it's thing, about 4-5 pumps, starts and dies, 2 more pumps it'll start, run on choke, droit into gear and drive away
