Fuel lines for my 70 Dart 440 500+ HP??

I think I reading you wrong so from gas tank to fuel pump~> forward use 3/8 aluminum. and from fuel pump to carb user steel braided?
As I said, mine fuel system is different because it's fuel injected engine with an in-tank pump. Yes, aluminum or steel line from the tank to the fuel filter, and braided line to the carb. You need to have a little braided segment at the pump to allow for flexure of the engine.
