I got the 3/8" steel brake lines, they bend well so I'm not sweating that. But they don't mate up to the 7mm (high pressure) fuel line.
For a 1911 L-Jet, is the 3/8" necessary? Won't 5/16" work ok? I just got to thinking that if the main delivery line is upsized a bit, does it stand to reason that the fuel rails and lines to the injectors need to be bigger? See where I'm going? I could get a bigger rubber line from the 3/8" but then have to neck down again at the pressure regulator. I'm trying to make some progress and I end up with more questions. I thought I'd just order some aluminum or SS line from Summit, but 5/16" and call it a day. Working on the car is not a good way to end a bad day. But I must press on...

5/16 is fine (fuel supply wise).

5/16 is what i used for my tunnel lines too. I think it is just sligthly bigger than 8mm. So, the 8mm inner diameter high pressure lines will fit fine with it.

I got the 3/8" aluminum tubing and some tubing-to-AN6 fittings . I redid the rear bulkhead to carb lines with AN6 braided stuff incl. pressure gauge and inline filter and PMO solid fuel bars last weekend. Gonna do the front cell-tunnel section within the next couple weekends.
