As long as the electric pump is mounted at the back near the fuel tank and mounted level or slightly below or slightly above the fuel level it will work like a charm.
Electric fuel pumps do have ability to "draw" fuel in on the inlet side.
A Carter P4070 makes for a very good axillary "pusher pump" to add onto a performance car with a engine mounted mechanical fuel pump.
The carter pump ensures the mechanical pump does not vapour lock and
sees a steady fuel supply.
You can drive with the electric pump off and switch it on when needed. You can even control it with a WOT "nitrous switch", on the carb,, controlled thru a relay.
