Does the Fuel Tank Cap Have a Vent Hole?

[Donovan]

The fuel tank cap has a vent hole. Below are the classifications of fuel tank caps: 1. Mechanical key opening type: This method is relatively complex and therefore rarely used. 2. In-car switch type: A more common method, which is more convenient compared to the mechanical key opening method. 3. Direct press type: This is the most convenient method among the three types of fuel tank cap opening methods. It requires no operation from the car owner, allowing the fuel attendant to refuel directly. For cars using this type of fuel tank cap opening method, the owner should ensure to lock the car when parked. Otherwise, the fuel tank cap can be opened if the central control is not locked, posing certain risks.
