MF140221
Fuel Return Line Bolt
Mitsubishi FUSO®

The Fuel Return Line Bolt, also known as MF140221, is a small but crucial component of a truck's fuel system. This bolt is used to secure the fuel return line to the engine block or fuel rail, preventing leaks and ensuring proper fuel flow. Made from durable materials such as steel or brass, this bolt is designed to withstand the high pressures and temperatures of a truck's engine compartment. Without this bolt, the fuel return line could come loose or leak, leading to decreased engine performance and potential safety hazards. When replacing this component, it is important to use an OEM or high-quality aftermarket part to ensure proper fit and function.
