ideas on securing these tectran hoses?

Here is my setup. I do extreme angles all the time. Been working great for years.

 

Another pic.

 

Its a violation by the DOT to have those lines touch the frame or deck

 

Mine are long for my wheelbase as well, with a skateboard. I have them wrapped with pipe insulation, then with the plastic that you have there. It protects them from my headache rack and catwalk. However, mine are not as long as yours and I still have them mounted with the springs near the top of my headache rack

 

That I did not know. The truck has been been through 3 level two inspections in two different states and nothing was said.

 

Yours are wrapped in that hard plastic, that's why they didn't say anything. It's protecting them and technically, they aren't touching the frame or deck

 

You have 12 or 15 feet?

 

Mine are 12 I believe, just the stock ones that come on a T680
