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

Early signs of a failing injector nozzle include rough idling and a slight decrease in engine power. If left unaddressed, the engine may begin to misfire, leading to increased fuel consumption and exhaust emissions. Continued operation with faulty nozzles can result in uneven cylinder wear and potential damage to pistons.

Installation Tip

Ensure the nozzle tip is protected from accidental impact during installation, as even minor damage can affect the spray pattern. Do not reuse old sealing washers; always install new ones to prevent fuel leaks.

Service Note

Inspect the fuel injection lines for any signs of leaks or damage, and consider replacing the fuel filter.
