I don't recommend passing fuel through it.
Instead of passing fuel through it, it is used as a Protective Tube to prevent damage to the surrounding area during wiring by passing twisted Stainless Steel Wire inside.
I often use this hose to hold small parts without letting fuel pass through, such as putting it under a battery to hold the terminal nut.
It is convenient to use together with Tie Wrap and Wire & may be self-satisfying for those who prefer this kind of Racer-like finish.
