I used a new stock tank, and installed the fuel pump on the sending unit. This makes it almost mandatory to use a surge tank set-up to mitigate air getting in the high pressure side of the fuel system due to no baffling in the tank though.

The surge tank style of EFI fuel system out performs virtually all of the aftermarket fuel tank modifications with regard to supplying air free fuel down to the last gallon or two.

The only tank set-ups that comes close to the surge tank set-up are a 4 corner snow mobile pickup systems that feed into the factory fuel modules that come in the Corvettes, Cameros and Cadillacs.
