I would never run them on a modern fuel inj. System. But in a low psi system properly routed. There will be no issue. Looks trick and will function flawlessly.

Last post I'll make, I promise.
If you want the look buy copper plated steel line and do that. Regular soft copper is a bad idea. Has nothing to do with pressure. Any vibration will slightly weaken the copper until you get a failure, even if you try to isolate it with rubber sleeving. There's a reason why nobody uses copper for fuel lines anymore, I think Olds was the last one back in the 60's. And if you are using compression fittings those will most likely be your point of failure. If you have GOT to have straight up copper than at
least double flare instead of using compression fittings.
Not trying to badger... just stay safe. Just because it looks good and seals now doesn't mean it will hold in the long term.
