Love efi and carbs. However, I'd never use that pump inline. Either a surge tank or an in tank pump. The supplied pump strapped to the frame rail is kind of a crappy solution IMHO. It's going to cost you more in parts to do it right.
Some vehicles came right from the factory with a frame mounted EFI pump. That badass pump Walbro makes that MadDart uses is total badassary and it's an inline pump. Long as you get it close to the tank as you can, it should be fine.
