Street/Strip fuel hose suggestions....

Well, it depends. LOL -10 is 5/8 on the "non transportation side". Then there are the "transportation" sizes. For what we do at work with hydraulic hoses, -10 is indeed 5/8, but I think that's different than transportation stuff.

Dash Sizing for Hoses and Tubes Explained

Typically in automotive plumbing when using AN fittings, -10 is 5/8. (next size up from -8 or 1/2")

Typically -10 hose is about .560" I. D., and the reason they say to go so big is because most of the fittings are a bit restrictive, and many have an I.D. quite a bit smaller (somewhere around .480" on most -10 fittings).

The -10 does indeed mean 5/8". But it's referencing 5/8" O. D. hard tubing, which is what this stuff was designed to be compatible to.
