I have a question about plumbing an external fuel pump. Do I need to run high pressure line from the tank to the pump, or just between the pump and the regulator?

You have to run high pressure line anywhere after the fuel pump. So from the fuel pump to the fuel rail, and on the return side from the regulator. The line from the tank to the pump does not have to be high pressure, but it must be rigid enough so it doesn`t get sucked flat.
