Edit: it was azdave earlier in this thread who said his replacement didn't last 5 years. @azdave: Was that a Clark's part? I hope Cal isn't selling bum parts just to guarantee future business.
But I don't like this particular hose. Also those "Total Seal" piston rings were also junk many moons ago. Never seated.
The filler tube connector hose that failed me was definitely a section of radiator hose. The new hose in your photo looks just like what I had.I found yet another one just like it in my parts stash and it is marked as a coolant hose and going in the trash. I think my failed part came from a vendor at the Palm Springs swap some years ago.
The new hose I purchased locally was by Gates and clearly marked as fuel hose. It is used in the RV market around here in longer lengths the get the fill tube connected to the gas tank. The Gates #24702 1-3/8" ID hose was a loose fit on the tubes but still worked perfect when the clamp was snugged. One foot of that will do three Corvairs.
