fuel line material

[CARR33]

i just installed a 16 gal fuel cell in the bed of my 67. it has -8 ( 1/2") fittings. i have plenty of the cheap steel braded hose, bit i dont know if i can run it from the tank ( installed in front area of bed) to the fuel pump on the engine, or should i run a section of some kind of hard line along the frame with braded line on the ends. i've heard aluminum get work hardened just from vibrations and cracks, i cant find 1/2" stainless, and i dont know about the effects of gas on copper. a friend tried a quicky fix on a 66 impala when he got multiple pinholes in the factory line and just ran a piece of rubber line from the tank to the pump and it didnt get very far before collasping. any ideas?

if you have enough braided line and it's rated for fuel i'd use that
