Jim Carter and other vendors sell prebent lines for your truck, but there will be problems. You wont get a perfect fit right away. One of the obstacles is there are at least three fuel pump models that work and they are all interchangeable. Problem is, the fuel inlet/outlet arrangement is not consistent. So, for your engine, the fuel pump is NOT normally straight in/out, but for your TRUCK, they are. If you go with stainless steel you will have a REALLY hard time bending them to work. Be sure to get the vac advance and fuel line for a 1957 truck, not a 1948.
I think you will be alot happier with your build doing them yourself. If you use the easier bending nickel lines that they sell at most auto parts stores, the bends are easy. If you are like me, its a good excuse to get more tools. And, they can be used for brake lines, fuel, PCV, everything.
