Genuine Bosch Fuel Overflow Hose 0928402212

A fuel overflow hose is a crucial component in a car's fuel system, designed to manage excess fuel that may escape from the fuel tank during various situations, such as refueling or thermal expansion. When the fuel tank is filled, the overflow hose allows excess fuel to be directed away from the tank, preventing spillage and potential fire hazards. This hose typically connects to the fuel filler neck and leads to a designated area, ensuring that any overflow is safely channeled back into the vehicle's fuel system or onto the ground in a controlled manner.

In addition to preventing spills, the fuel overflow hose also plays a role in maintaining proper fuel pressure within the system. By allowing excess fuel to escape instead of building up pressure, the hose helps to avoid potential damage to the fuel tank and associated components. This not only enhances the overall safety of the vehicle but also ensures optimal performance of the engine by maintaining a balanced fuel supply. Regular inspection of the fuel overflow hose is essential for vehicle maintenance, as any cracks or leaks can lead to fuel wastage and increased emissions.
