Patrick brings up a good point about any rubber line feeding into the mechanical pump could be damaged from Ethanol and collapsing under suction while the electrical pump pressurizes it and forces it open. Something still wrong with the 9 PSI however.
Yes, feeding a mech pump with an electric one is not unusual. I've had that arrangement on a Corvette for 25 years now. You can use the electric to prime the carb before starting if the car has been sitting a while.
