So, I'm looking at new fuel line for the Duster. It comes in standard steel or stainless. A few years back I installed a new steel line from tank to carb and it didn't bend that easy (comes folded in half.) Are the stainless lines harder to bend and maneuver into place or is there no real difference? Thanks for any help
New 5/16 fuel line??

In. my experience, which isn't a ton, stainless is harder to bend and seal.

Stainless is harder to bend and also harder to seal (if you use flares which you won't be) You are looking at inline tube?
You seem to be asking for instruction on how to straighten or bend hard line without kinking it. Look for videos on youtube or take your new line to an aircraft mechanic at your local small airport or a hydraulic shop and ask him to unfold it for you for a few $$.

Stainless it harder to bend and if you need NPT fittings use Swagelok compression fittings.
With the steel lines, they are away softer and easier to bend, so much so you can kink them. I used the Inline kit and used a large, long 2x4 to work them out on pressing the radius on the work and walking the bend out flat. It didn't take long, this was tank to engine bay.

In my '65, I just installed the Inline Tube 5/16" gas line and all the 3/16" brake lines in standard coated steel. The long lines unfolded nicely just by laying it out on the floor and gently bending it straight. Stainless steel is very hard to work with, and the Inline kits are good, but not perfect. You will be doing a lot of adjustments. Even with standard steel lines I had to use my hand tubing bender in a few places to get it right. Read and follow the directions that come with the kits.
Yea, I bought the steel line from Inline (tank to engine) a couple years ago, and I remember adjusting it a lot. That's why I was thinking maybe I shouldn't get the stainless, but it is a better product.
It really depends on how your car will be used. If you plan on driving it year round in areas that have snow and ice, and salt is used on the streets, it may be worth it. If not, standard steel will last a very long time, and probably will outlast you. I think a better argument can be made for stainless exhaust systems than brake and fuel lines due to the heat its exposed to.
Edit: I just noticed you are from Florida. If you're near the coast there could be an issue with salt air so that is a consideration.

I use stainless on all cars. It is harder to work with but they are lifetime pieces for your car.
One thing you can do to help sealing, is to use flare / inverted flare copper gaskets from the HVAC/R industry.
Just for EG to show you what they are

Yea, the gas tank on the car was rusty, so I replaced it a few months ago. I'm in the process of getting it road worthy, so I replaced the Carb, rubber fuel lines, and filter. I noticed a lot of rust particles in the line by the filter. I'm guessing the old line has some rust in it, so I'm going to replace it with a new steel line.
Steel fuel line [ & brake line ] tube is made from Bundy steel. It is a soft, pliable steel that bends easily, is easy to flare the ends for a good seal, but does not crack. The soft nature allows for excellent sealing of the flared ends to fittings. S/steel is very hard.......
