Depends.  I see your point but if you live in the salt/rust belt and don't like to be left stranded..or if in the case of brake lines..enjoy stopping, it may be worth your while.  Around here, I've seen uncoated steel lines last as little as 5 years.  Main culprit is where salt water pools in the rubber mounts that attach the lines to the underside of the body.

You will spend more time, money, and effort installing fancy lines than 
replacing the lines twice with the 5/16" steel line and compression 
fittings. Also, the fuel lines will be the least of your concerns when 
these cars are 25-30 yrs old and they go again.

> That was me but I've since found out that you can also get a fuel-rated copper-nickel line called kunifer lines. (90 % copper and 10% nickel). Easy to bend, corrosion resistant and rated for up t0 4000 psi. Apparently used on Ovlovs since the '70's. I've sourced it at a local hose and fittng shop so I think it should be widely available. Cheaper and easier to work than stainless too.
