FAQ

1. How do I confirm if the DLLA146P768 nozzle fits my engine?
Please check the existing part number on your old nozzle. The primary numbers to match are 093400-7680 or DLLA146P768. Also confirm your engine model (e.g., Isuzu 4HK1). If you are unsure, please contact our support team with your engine serial number or machine model for verification.

2. What is the recommended installation procedure for this nozzle?
Installation should be performed by a qualified diesel technician. Ensure the nozzle bore and sealing surface are clean. Lubricate the O-ring (if applicable) with clean diesel fuel. Torque the nozzle holder to the manufacturer’s specifications. After installation, bleed the fuel system to remove air and check for leaks during engine operation.

3. How should I store spare nozzles?
Store unused nozzles in their original packaging in a cool, dry place away from direct sunlight and contaminants. The recommended storage temperature is between 10°C and 30°C. Avoid exposing them to moisture or corrosive environments to prevent damage to the precision surfaces.
