Stainless braided fuel hose is popular on boats. Some surveyors insist on it (fireproof - probably). I hate the stuff. Looks lovely outside but you have no idea what's going on under the shiny stuff. Seen a few hose failures that appeared fine visually. For boat fuel (diesel) privided the tank is below the engine I use clear nylon with compression fittings. You can see whats going on, especially if there's air in the system and, being non-gravity, in the event of a fire no fuel is lost to make things worse.
Back to motorcycles - for oil pipes I detest the flexible, reinforced nylon some use. Looks rubbish, turns yellow and goes hard. My preference is black oil-proof rubber hose as sold for fuel hose plus either tiny jubliee clips or, preferably, crimp clips.
