1. Prepare for safety beforehand
- Stop all oil transfer or pumping operations on the fuel transfer tank to avoid fuel leaks or pressure fluctuations.
- Remove open flames, high-temperature sources, and other hazardous materials from the vicinity of the equipment.
- Wear protective equipment such as oil-resistant gloves and safety glasses.
- Prepare necessary cleaning tools, such as a soft brush, compressed air equipment, and dedicated drain cleaner.
2. Clean the vent
- Locate the vent, usually on the top or side of the fuel transfer tank.
- Remove the dust cover or filter from the vent using appropriate tools if necessary.
- For minor blockages, gently brush the inside of the vent with a soft brush.
- For more severe blockages, use compressed air with moderate airflow.
- If needed, pour a small amount of specialized drain cleaner into the vent according to instructions.
3. Complete the clearance check
- Check if the vent is clear by feeling for airflow or observing during refueling.
- Look for any abnormal pressure changes or fuel spillage.
- Check the vent's filter and dust cover for damage and replace if necessary.
- Verify the stability of the internal pressure of the fuel transfer tank.
4. Strengthen subsequent daily maintenance
- Establish a regular inspection mechanism for the vent.
- Regularly clean any adhering dust, oil, and other impurities.
- Develop a regular cleaning plan based on usage environment and frequency.
- Avoid adding fuel containing large amounts of impurities to the tank.
- Protect vent components during daily storage and use to avoid damage.
