looks pretty!

I used stainless braided the whole length on my big block truck, but using hard line for part of the run would definitely allow "closer" routing around headers, without fear of it sagging and contacting the exhaust.

looking at yours reminds me, make sure your bleeder valve is higher than the TO bearing, and does NOT angle down at all.

I had a heck of a time when I tried to bleed mine because it was so short, that it angled down as it came out of the bell housing, and that downward angle made the fluid run out and air would bubble up into the hose, and I had a heck of a time getting the system bled to give a good firm pedal. I finally used a much longer bleed line, that allowed me to bring it back up the firewall so that the bleeder screw pointed up instead of horizontal or down, which prevented fluid from freeflowing out and air filling the hose.
