Before installing replacement injectors, it is strongly recommended to identify and correct the root cause of the original failure. If the issue is related to fuel contamination, poor fuel quality, or improper fuel handling, the entire fuel system must be thoroughly cleaned and flushed prior to installing new injector(s).

Replacement injectors should remain in their protective packaging until the moment of installation to prevent contamination or accidental damage.

Before starting the engine, the fuel system must be properly primed to ensure adequate lubrication and pressure.

Failure to follow these installation guidelines may lead to premature injector damage or failure, which may not be covered under warranty.
