Is it dangerous if fuel overflows during refueling?
1 Answers
Fuel overflow is indeed dangerous for the following reasons: 1. Spilled fuel causes waste and can easily ignite in hot weather, becoming even more hazardous when exposed to open flames. 2. Overflowing fuel may soak surrounding components, potentially causing damage. 3. Fuel is highly volatile, and the evaporation process generates gases. When the tank is filled to overflowing, there's insufficient space to contain these gases, especially during bumpy rides, leading to tank expansion. 4. If the tank's vent is blocked, negative pressure may develop, potentially causing fuel supply issues. In severe cases, fuel might enter the intake manifold and soak the spark plugs, preventing the vehicle from starting.
