I had a '65 3/4 ton a few years back that I dropped a Holley Pro-Jection sytem on. Since it required high pressures and a return line I opted for hard lines.
Being in the aviation industry I could cheat & had access to all the neat tools & equipment to do things right. However, I can tell you that going to a local race shop will yield the same results. most good shops have the lines on hand, & if they cant get the flared fittings done any local hydraulic shop or a aircraft maint shop at a nearby airport can help you out as well.
You can get a nice finish from aluminum lines & fittings without the expense & fun of handling stainless lines. I did opt for stainless due to the pressures I was using, but for a standard gravity feed & 5-PSI pressure, aluminum will do the job.

At any rate, getting your truck to a shop that makes lines will make life easier by far. they can bend the lines to fit then & there, and you can take it home to assemble at your leisure. Worth a shot anyway

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
