Does the Fuel Pump Automatically Shut Off When the Tank is Full?
1 Answers
When the fuel tank is full, the pump will automatically shut off. Gas stations commonly use self-sealing fuel nozzles that automatically trip when the tank is full. These nozzles utilize a special structural design in the reflux valve assembly to create negative pressure within the pressure-sensing system. Precautions for refueling include: 1. Refuel in the morning or evening to avoid direct sunlight at noon; 2. Add fresh fuel before long trips; 3. Do not exceed the tank's maximum capacity; 4. Avoid using electronic devices; 5. No smoking; 6. Turn off the engine and power when parked. Solutions for misfueling: 1. If higher-grade fuel is accidentally replaced with lower-grade, short-term use won't harm the engine; 2. If gasoline is mistakenly added as diesel, contact a repair shop immediately to clean the fuel tank and lines, and conduct a thorough engine inspection—do not start the engine to avoid damage; 3. If diesel is added as gasoline, replace the fuel immediately.
