High-Pressure Line Kit - Cylinders 1-3
Detroit Diesel

This set for cylinders 1 through 3 includes a high-pressure fuel line crafted from stainless steel, designed to deliver fuel efficiently and safely. Its length of approximately 277.10 mm is optimized for precise routing within the engine bay. The component’s high burst and working pressures—4000 bar and 1100 bar respectively—are indicative of its capability to handle the intense forces generated during fuel injection. The stainless steel construction ensures resistance to corrosion and thermal fatigue, which is vital for maintaining long-term system integrity. Such a line plays a pivotal role in ensuring consistent fuel pressure, thereby supporting optimal engine performance, fuel economy, and emission standards. Properly maintained and installed, it reduces the risk of leaks and failures that could lead to costly repairs. For technicians and fleet operators, sourcing this part from an experienced provider guarantees compatibility and durability in demanding conditions.
