This used genuine OEM BMW Fuel Tank Breather Line / Hose, part number 8663978, is the plastic vent hose from the tank to the EVAP system. On 330i and M340i models with the 2.0L turbo or 3.0L six-cylinder (including mild-hybrid variants), a cracked or clogged line will trigger a check engine light for an EVAP leak and cause a strong fuel odor. The hose allows air to enter the tank as fuel is drawn out, so a damaged piece can also make the pump shut off prematurely when refueling.
