I used a surge tank mounted to the chassis under the bed floor.
It’s fed from the in cab tank by a low pressure pump and feeds the efi high pressure fuel. A return line goes back to the surge tank from the efi and a return from the surge tank back to the in cab tank. I can run it to almost empty without fueling issues.
I didn’t like the idea of having a surge tank in a hot engine bay and potential ramifications of a frontal collision. Having said that I still have an in cab tank, so take that for what it’s worth.
