It's the fuel line you are looking for.
sturdy well made line, the coating is nice and easy to bend into shape. Tight corners may kink but that's to be expected.

Working well for me, would purchase the same again
Seems to be working great. The only reason I’m not giving 5 stars is that I really don’t know how to compare it to similar products. This is the first time I’ve worked with steel brake line. In my case, I’m actually using it for fuel line on a tractor, using compression fittings. I’ve been cutting it with a pipe cutter - same type used on copper plumbing pipe - and that works good... leaves a nice square cut, although it’s always a good idea to deburr the ID and OD of the cut before fitting it up. The fittings go on fine - there doesn’t seem to be any problem with fit due to the PVF coating. The coating stays on where I’ve bent the tubing. Hopefully this will keep rust away and this fuel line will last the remaining life of the tractor.
