vapor lines, if I want to replace them what do I use? Options

[worn]

When I was stripping the tub I wasn't as respectful to the vapor lines running under the rockers from engine to tank as I might have been. Also I am not sure where they all are (no smiley for what an idiot).
At any rate they seem to be a PVC material that is either supposed to be kind of stiff or has hardened with the age. They look black, and I suppose they may have started that way. Other than that they look like tygon tubing.
I can find no replacement source. I probably won't have space for the catalytic converter in the 3.2, but I see no reason not to use this device for reducing emissions. But what should I use?
Great thing is that this group will find me an answer (of some sort). Thanks so much!

sorry for the highjack but somewhat related, is this why the tank can build up pressure or vaccum? is it the lines being blocked or the charcoal canister? ive read where the charcoal needs to be replaced too,
btw the airlines from a truck seem like a good idea.

The tank is vented via the charcoal canister and expansion chamber. As you know, fuel will vaporize with heat. The fumes are supposed to be taken back to the air cleaner to be burned in the engine.

If you draw a vacuum (negative pressure) on the tank, the vent has been capped off.

The small hose from the filler neck connects to the expansion chamber which in turn is connected to the charcoal canister. On my car I run the vent hose to the bottom of the car ... yeh! I'm not "green".

The charcoal can become saturated with fumes and lose it's effectiveness. I thought by placing it in an oven it can be made good again, but it can be replaced.
