Fuel hose text

[Gimmea250swb]

I'm refreshing my 69 Z/28 (10A Cowl tag).  What markings are correct on the fuel hose? What's on there now doesn't match what I'm finding online:

The one I pictured in the thread referenced above was a return line, it was 1/4" or  5/16" IIRC.
The original 3/8" lines I removed when I took the original fuel pump off my 71 Corvette were exactly as the one Steve Shauger showed in the above linked thread, they had no markings whatsoever.
