The BMW Fuel Tank Breather Valve (part number 13907643106) plays a crucial role in the vehicle’s fuel system. It regulates the pressure and vacuum within the fuel tank, ensuring that fuel vapors are properly managed and directed to the intake system. This helps maintain optimal engine performance and prevents issues like hard starts and rough idling.
Functionality
The BMW fuel tank breather valve (part number 13907643106) plays a crucial role in the evaporative emissions system. It helps manage fuel vapors by directing them from the fuel tank to the intake manifold, where they are burned during combustion. This process prevents the release of harmful vapors into the atmosphere. Additionally, the valve maintains proper pressure within the fuel tank, ensuring efficient fuel delivery and preventing vacuum-related issues.
