6N5124 Lines Gp-Fuel — Cat 120B 120G

This fuel lines group is a crucial part of the engine's fuel delivery system, designed to safely transport diesel fuel from the tank to the injection pump and injectors. Manufactured to withstand fuel pressure and resist degradation, it ensures a leak-free and reliable fuel supply, unlike old or damaged lines that may crack or develop leaks. Operators might notice fuel leaks around the engine, a strong smell of diesel fuel, or engine stalling due to fuel starvation when these lines are compromised.

Installation & Application Notes

Use clean, filtered fuel — fuel injection components have micron-level tolerances. Prime fuel system before cranking to avoid dry-start damage. Replace fuel filter whenever servicing injection components. Calibrate injectors after replacement if equipment has ECU.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of failing fuel lines may be a faint smell of diesel fuel or minor weeping at the connection points. If ignored, leaks can worsen, leading to significant fuel loss, potential fire hazards, and engine stalling due to air entering the fuel system. In severe cases, a burst fuel line can cause a sudden loss of power and uncontrolled equipment operation.

Installation Tip

When installing new fuel lines, ensure all connections are clean and free of debris to prevent leaks. Avoid twisting or kinking the lines during installation, as this can restrict fuel flow and lead to premature failure.

Service Note

Inspect all fuel filters, the fuel tank, and the fuel transfer pump for any signs of contamination or wear when replacing fuel lines.
