The original tunnel lines are made of polyamide a type of nylon thats resistant to all types of fuel including ethanol and methanol.
There are compression fittings made for it so you could put Lens hoses on them or make your own.
Boats usually use it for the fuel tanks.

An example of the fittings.

and of course there's always a you tube video...

My car didn't use a cloth braided hose on the bottom of the tank. I never liked that stuff because it hides dry rot cracks in the hose when it gets old.
The bottom tank hose on mine was smooth rubber and it did show dry rot cracks so I took it to Mako hose and they gave me this hose to replace it that's resistant to ethanol and most other solvents.
He said his drag race customers use it in the cars running E85 or whatever.

I don't remember what it's called but I used it on the top vent line too. Says it can handle 300psi so it must be good.

They look a lot easier to get in than stock lines -- strait shot. Does he have some sort of threaded end that connects to the hoses to pull them through the tunnel?

Yes, Len now provides a threaded coupler to connect the new line to the rear of the old line. I provided him the information where I made my own from an old M14 female fitting nut. Then you just have to pull it through from the front. However, it still gets hug up on stuff going through, so you have to have the front and rear tunnel access holes open which means you have to remove the center console to fold back the carpet on the tunnel up forward. I also removed the shift lever. One of those free Harbor Freight LED flash lights fits nicely in the tunnel to see (with a mrror) where your at when the connection gets hug up. You just have to use your fingers and/or screw driver to help it by the support brackets/sharp edges that catch it. Also, at the forward end of the tunnel just forward of the gear shift housing location there is metal tab similar to the metal tabs that hold the wiring harneses in place that needs to be bent down to allow the hoses to go by. You can search for threads where others have accomplished this job.
