Most were rigid plastic along the frame, metal from the pump to the carb, and rubber at all the junctions.
Lots of people do rubber, but some bend up their own hard line. There are kits available that you might have seen already, from some of the vendors, but they are not all one long piece as far as I know. There are junctions, likely to make them easier to ship.
While there might be some 1/4" hose pre-molded into a U-shape, that looks like what everybody I know uses and just a piece of hose doubled over.
Those are your evaporative emissions vent tubes though, for '70 to '75 Broncos. And are good things to keep functional if you can.
If yours was originally equipped, your gas cap will be "non-vented" accordingly. If this is a swapped-in tank to an earlier year though, there should be no venting issues as the fuel level goes down from use.
Keeping them intact requires a charcoal canister, but if you're going to be parking this thing in the family garage it's usually considered a good thing in the long term.

Thanks Paul, good stuff.
