Please refer to the "Step-by-Step Installation Guide" on our product details page, which contains detailed installation instructions.

The installation environment must be dust-free; lubricate the O-ring with clean machine oil before installation to prevent oil leakage; and ensure the O-ring is installed correctly.

This is common due to air trapped in the high-pressure oil rail. Cycle the engine in short bursts (no more than 30 seconds) to purge air. It may take several attempts to stabilize pressure.

If unsure about compatibility, please provide your Engine Serial Number (ESN) for free verification.

• Cylinder Cut-out Test: Using diagnostic software (ET), shut off cylinders one by one and observe engine speed fluctuations
• Fuel Rail Pressure Test: Check for internal leaks preventing system pressure buildup
• Back-leakage Test: Excessive back-leakage indicates worn internal control valve assembly
• Visual Inspection: Check fuel injector nozzles for carbon buildup, blockage, or corrosion
