Looked for this kind of hose for a long time. Use it for motorcycle fuel line where it has to fit in tite places with turns. 100 psi rating so works with motorcycle fuel injection.

Seems to fit my application well, as a flex coupling between hard (aluminum) ~5/16 OD fuel tank vent lines. Seems a robust material, very flexible. Used on an experimental vintage warbird.

Excellent 0.25 ID fuel hose. Warming the ends in cold weather makes pushing onto fitting easy.
