Still lots of parts plqces selling fuel hose that cant take ethanol or only 2% (its around 6 to 8% now i think is common?). Even worse some is badged as taking current levels of ethanol but cant, and also not uv stable. So you'll have brittle rotting fuel hose in 3 to 6 months. Buy a fire extinguisher!
I finally found some that seems to last, currently on 12 months and still feels rubbery, came from a local bike mechanic who gets it from an Italian manufacturer but thats all i know
All our petrol here has a ton of ethanol - it's diabolical for carbs. Turns all the brass jets black and gunks everything up. Also eats the shit out of any rubber parts.
