Just fabricated the flanges so it would fit perfect in the brake shield.

Here is where I got the flanges.

Section of 2.5 of this

On the connections I used Tie wraps on them that are good for UV rays and extra strong. I had them from my company. I have to find the part number, I know they are not cheap. I also wanted to use the tie wrap on the bumper so I would not crush it by over tightening it. I then followed by the tie wrap with gorilla tape so it would not slip. Depending on your wheels width I temporarily mount the hose and go wheel lock to wheel lock with the steering wheel to find the best route for the hose. Make sure that the hose has extra slack in it to provide extra length. Make sure you store this extra length in a bend. I also wrapped specific sections of the pipping with gorilla tape where it would rub for protection.

Hope this helps.

 

It is above the diffuser so that should help...
