That is not what work hardened means. Simple vibration is what does it. Engine running, driving, etc. And PSI is not part of the issue here.
IMO you are asking for a fire if you plan to drive it that much. Too many people much smarter than I am have told me that. If that is a risk you are willing to take then fine. But be aware of the potential consequences. I think there is a reason GM said do not do it.
I'm not a fan of aluminum on a street car either, but not for the same reasons. It's abrasion/puncture resistance issues. I have personally had an aluminum line - an OE coolant line - punctured by road debris. It didn't even mark the steel floor it hit too. So I have BTDT. There is a reason OE fuel lines were steel with rock guard (that spring covering). The newer 'plastic' (not the right term) are also fairly strong and covered in sensitive areas.
I am fairly certain that the aluminum grade used in airlines is not the same as the stuff you buy at jegs, etc. And those lines are not exposed, they are inside the fuselage, wing, etc. So from where I stand it is a poor comparison.
Now if you fuel lines are totally out of harms way - which means not exposed anywhere under the car, sure you can do that. But not a lot of vehicles are setup that way.

Can't wait for a huge flaming car fire. I'll be sure to post pics of updates when I rebuild. I'll also be sure to use plastic lines when I do the 2nd full resto.
