I made new oversize fuel lines for my first ae71, was not worth it. Maybe the least enjoyable mod I've ever done. Just write down the pip sizes for feed and return, take the pump bracket with you, ditch the expensive raceworks stuff and go to an industrial gasfitting supplier like IFS and just buy what you need off the shelf. They have everything, hose to barb, taper fittings, banjos, hose adapters, push lock, metric imperial and they can make a fitting if you're really stuck.
