Homer,
Complicated hard lines are not easy to make and if you can do it it showcases your craftsmanship and enhances the appearance of your project.
The stainless tubing that Jerry recommends probably cannot be double flared for common flare connections so AN fittings may be required. Stainless tubing does look very nice, though.
When I restored my '36 Chevy pickup over 40 years ago I used stainless tubing for gas lines and for the vacuum advance line from the carburetor to the distributor and it still looks as good as the day I installed it.
