Fuel Line - Common Rail Return
Detroit Diesel

This steel fuel line features an 8 mm inner diameter coupled with a 10 mm outer diameter, designed specifically for common rail return systems. The 1 mm wall thickness ensures durability while maintaining flexibility within tight engine compartments. Its precise center-to-center length of approximately 618 mm enables accurate routing back to the fuel tank, facilitating efficient fuel return flow. Constructed from high-quality steel, this line resists corrosion and high-pressure stress, ensuring long-term performance under demanding conditions. Its critical role lies in safely channeling excess fuel from the rail back to the tank, preventing pressure build-up that could impair engine operation. Proper installation of this line is vital for maintaining optimal fuel system balance and avoiding leaks that could lead to performance issues or safety hazards. This component’s robustness contributes significantly to engine reliability, which is why Source One Parts Center emphasizes its importance in comprehensive fuel system maintenance and repairs.
