7C6525 Lines Gp-Fuel Injection — Cat 3408 3412

These are fuel injection lines that deliver high-pressure fuel from the injection pump to the engine's injectors. Manufactured from robust materials to withstand extreme pressures and temperatures, they ensure consistent fuel delivery unlike worn lines that can leak or deform. Operators may observe rough engine running, loss of power, or visible fuel leaks around the injection pump and injectors when these lines fail.

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

Initial symptoms include a noticeable decrease in engine power and potentially a rougher idle. If ignored, fuel leaks may develop, leading to a fire hazard and further performance degradation. Unaddressed line failures can result in incomplete combustion and potential engine damage due to inconsistent fueling.

Installation Tip

Carefully clean the connection points on the injection pump and injectors before installing the new lines to prevent contamination. Avoid bending or stressing the lines excessively during installation, as this can weaken the material and lead to premature failure.

Service Note

Inspect the fuel injectors and the fuel injection pump for any signs of wear or leakage while replacing the fuel injection lines.
