[T3] New brake line help

[Max Welton]

So the guy that took this car apart lost the center tunnel brake line.
I have a new one from ISP and the tubing bender but I need to know
what it's supposed to look like. I presume it passes through the hole
under the master cylinder and uses a grommet.

Also, does the tubing just lie in the bottom of the tunnel? Seems like
it would rattle that way.
