Not really 15 hours today, I am adding up lots of little times and big frustrations. But finally the fuel and brake lines along the spar are finished and bolted into place (not properly torqued yet though).
A long and frustrating process for me. Others have clearly done this faster and easier but anyway, it's finally done...at least until the distant future when it's leak-tested.
The best way finally was to take a long segment of line and push it through, bending by hand as needed.

Left side. Lines don't touch, but are close, wrap is to prevent Al-Al rubbing.
