Otto, I’ve got a rocker switch wired up so I can toggle to the fuel level sender in either tank. The driver side tank is the primary tank with its in tank pump delivering fuel to a GM TBI system I’ve grafted to a 327 CI V8. When the primary tank gets low I’ve got another switch which operates an in tank transfer pump in the passenger side tank to feed fuel back to the primary tank. Filler neck is under the bench seat at the driver side. I’ve got to open the driver door to fill ‘er up: both tanks simultaneously.
