Review on 6AN Flexible Rubber Hose Clamps - 4Pcs/Pack Black Connectors for 3/8 Fuel Line - Ideal for Fuel, Oil, Diesel, Gas, Air and Water Hose Tube by Michael Skerving

I was hoping this would make a nice aesthetic addition to the bike I am building. The internal distance from the end of the clamp body to the clamp itself is too great to be used as a fuel line on a motorcycle. I'm not sure when they list it as such. waste $15.
