Description
The Bosch 0445130020 Fuel Return Line Assembly is a drop-in replacement for the contaminated or clogged line in your GM Duramax truck. The rubber hoses are prone to wear over time and can start to get hard or brittle, particularly on trucks with higher-milage. Signs of deterioration such as small cracks can show on the inside of the hose, although the outside of the hose may look fine. This return line assembly uses high-quality materials to last for many years to come.
