Like 02, when I've done it, I like to not flare it as much as him...but bubble the end of the line with a flare kit. Similar to what he did, just stopping once the line starts to bubble outward. Then use two fuel injection hose clamps per connection point to quadruple insure yourself based on the pressure running through the lines.
I use some sticky tacky rtv around the pipe and slide the over it typically 1-2inches an use the same clamp u do. I like the extra insurance
