Upgrading the fuel tank

I am upgrading the fuel tank in the 71' Dart due to the mechanical pump eating a push rod.
I first tried another push rod but the cam lobe was too damaged, next I tried a Speed master external electric fuel pump that made it to the gas station and back and then died. Not wanting to go that route again I have purchased a Tanks Inc. efi tank. My question is for anyone who has done this conversion, have you had any starvation issues
with the internal electric fuel pump? The tank has a boxed section around the pump and sender area that looks to be around 1 gallon in size. I will be using the regulator that came with the Speed master kit to step down the pressure for the carb along with a return line.
The efi pump and tank have vent lines that will be tied together and vented above the tank.
Any thoughts or issues to look out for?
That box section is there to eliminate the pump pickup running dry on hard acceleration, cornering or braking it keeps the pickup submerged. Great tanks use one for the EFI setup. Nice powder coat finish . If you have a breather line on your filler tube just tee into that and block the breather outlet on your tank and use one from the pump.
