You definitely don't need a setup like the Edelbrock sump.
You've found a pickup with return port and the Corvette filter/regulator is designed to be mounted near the tank.
Run the walbro online pump mounted out back by the tank, the filter/regulator right after it. The you'll run the outlet of the regulator to the front of the car and the return from the regulator back to the tank. It should be a fairly short run, less than a foot or two.
Vendors sell modified versions of that filter/regulator with AN fittings on it, or you can run efi rubber line and clamps for the return, I'm not sure if that's nhra legal or not. The run up front should be hardline with short sections of efi rated line as jumpers. Like @famous bob mentioned, check summit or jegs for efi rated, braided jacketed nhra legal hose for those portions
