Plastic tubing from charcoal canister that runs through rocker Options

[john77]

I'm almost finished flaring my car and when I removed the tubes from the charcoal canister that thread through the rocker supports back into the engine bay the old brittle plastic pretty much disintegrated in my hands.

I'm assuming I can use any similar ODi plastic tubing, does anyone have any suggestions on what they've used to replace this?

And, do they really need to thread all the way underneath the rocker into the engine bay?

I'm guessing they routed them that way so any fumes were released behind the cabin rather than in front of it, so the driver didn't get a lung full.

But given I never drive with my roof on I'm not too bothered about that, so other than that, are there any cons to me running much shorter tubes into the front fender and terminating them there?
