Welcome Ms Griff....
A word about electric fuel pump wiring. Keep in mind you don’t want a ignition on fuel pump running gas on you while your rig is upside down in a ditch. GM used an oil pressure sending unit in the early days so if motor was not running it would shut off. (Vega) . Chrysler used an asd relay that was pcm controlled as did ford . Have to think a bit about how to control on non computer engine. Maybe alternator triggered control relay on 13-14 volts?
