Can copper be used for fuel line?

Longgone said
My flaring tool will only do soft metal (like copper) and I have a ton of it laying around the garage. I have the tools and the material and that`s why I was asking if it was used. I tried using steel and I can`t flare it without the edges cracking and I`ve also had a hard time making the sharp bends I need to get around the distributor and down to the pump. I guess I`ll just have to buy a steel flaring tool and some line to bend the piece I need. Boy, there`s just NO saving money at this hobby ,huh!

I installed Aluminum fuel line on a Mopar I had years ago from the fuel cell,electric fuel pump,to pressure regulator to carb and it was easy to flare. I got a roll of it out of Summit. I didn't have a bending tool either just bent it by hand. Used the rubber coated mounting brackets. Summit also.
