I'd say "is there a torque spec included with the new lines," but that would be pretty tough to measure. I guess you could maybe use a crows foot. I understand worrying about stripping the Al. Presumably, the line has flare fittings on both ends?
Good luck.
When I read your post, this is the first thing that popped into my head and I can't stop chuckling.
