A bit extra.
If you are having problems with the cooler lines.
I use 5/16 steel brake lines with the steel coil around the exterior.
They can be bent, twisted, cranked on and not kink.
Plus the steel coil protects them from abrassion.
They come in various lengths. A 4 foot section will do one line.
But then in Canada it wouldn't be a 4 foot section eh.
It would be in millipedes.
