This genuine BMW fuel tank breather hose / line, OEM 7640120, is a used part removed from a donor vehicle. Also known as a fuel tank vent line, it maintains proper tank pressure and prevents vacuum buildup during fuel delivery. On the 0.6L range-extender engine (BEV REX), a failing hose can trigger a check engine light or cause fuel odor.
