Fuel Line Return
Detroit Diesel

This steel fuel return line is vital for managing excess fuel within the system, directing it back to the tank efficiently. Its 8 mm inner diameter and 10 mm outer diameter facilitate high-volume return flow, reducing pressure build-up in the injection system. The 1 mm wall thickness offers strength and resistance to internal pressure and external impacts. With a length of around 494.70 mm, the line is designed for optimal routing within engine compartments, ensuring minimal interference with other components. Its corrosion-resistant steel construction guarantees durability over extended service life, even in harsh operating conditions. Proper return lines are critical for maintaining fuel system balance and preventing pressure-related issues that could impair engine performance. Source One Parts Center recommends using precisely engineered lines like this to uphold system integrity, prevent leaks, and support efficient engine operation in heavy-duty diesel applications.
