Top side how I plumbed it.

A couple questions.
Why the regulator just out of the tank?
Why drill through the frame, why not just run them on the inside frame rail up to the front?
Why run the line up the inner wheel well? I thought that was dangerous (debris/tire failure)

Definitely not knocking any of your work, you’ve done amazing work for sure.
Just wondering thoughts behind your process.
Thanks for the pics!

Wally.
