Airtex fuel pumps

Obviously if you use the switch, you've got to provide power to the pump until you've got oil pressure (probably before cranking to fill the carb). Older Chrysler products had a timing relay that energized the pump for 5 seconds after the ignition was energized, or when the starter was activated. That would be perfect but I can't find one.

Thanks Ross....but I've got a '40 Coupe and was just wondering where people prefer to pull the power for the switch, or pump? From the coil side of the ignition switch? Should a relay be used if not using the Holley switch?
