OEM Leak Off Hose 6420705681

A fuel overflow hose is an essential component in a fuel system that helps to prevent fuel spillage and potential hazards. This hose is typically connected to the fuel tank and serves as an outlet for excess fuel. When the fuel tank is filled up beyond its capacity, the excess fuel flows into the overflow hose instead of spilling out onto the ground or onto other components of the vehicle.

The primary function of a fuel overflow hose is to redirect the overflow of fuel away from the tank and into a designated area. This helps in preventing fuel leakages, which can be hazardous and pollute the environment. The overflow hose redirects the excess fuel towards a safe location, such as a charcoal canister or a fuel vapor canister, where it is safely stored until it can be recycled or disposed of properly. Overall, the fuel overflow hose plays a crucial role in maintaining the safety and efficiency of the fuel system by preventing fuel spillage and minimizing the risk of accidents or environmental damage.
