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.
