The std 3/8 lines that these things run are plenty big enough, particularly when there's 60psi of fuel pressure behind it. Realistically, you can easily run over 350 rwkW's with the std 3/8 lines (that's well over 400 kW's at the flywheel).
Be very careful about going to larger fuel lines unless you are running big pumps. The extra volume in the lines can actually reduce the efficiency and cause pressure drops, (not good). The extra volume of fuel weighs more and under heavy acceleration this extra weight, puts more load on the pump. It's a catch 22 really, because under heavy acceleration you require more fuel, but you are actually trying to force the fuel back down the lines due to your acceleration g loads.
With a std pump set-up, stick to the std size lines....

Got ya Plums....standard pipes it is. Thanks heaps.
