Where is the air vent of the Volkswagen fuel tank cap?
2 Answers
The air vent of the Volkswagen fuel tank cap is located near the fuel filler neck. The fuel tank cap can only be opened when the vehicle is unlocked. Introduction to the fuel tank cap: The fuel tank cap refers to the box on the car used to store gasoline. It is square in shape, made of stainless steel, and has excellent sealing. There is only a small circular opening, about the size of a bottle cap, for easy storage. It is generally located at the rear of the vehicle. Precautions for refueling with the fuel tank cap: When opening the fuel tank cap to refuel, the fuel nozzle must be correctly placed inside the filler neck. Otherwise, fuel may overflow or splash out of the tank. Overflowing or splashing fuel can cause a fire and burn people. Do not enter the vehicle while refueling. If you must enter the vehicle, close the door and touch a metal surface before touching the fuel nozzle again to remove static electricity from your body. Otherwise, sparks may occur, which can cause a fire during refueling.
I've been driving a Volkswagen for several years, and the fuel tank vent hole is usually located on the fuel cap itself—a small hole on the inner side near the center. I remember one time when refueling felt particularly difficult; the pump nozzle kept getting stuck. It turned out the vent was clogged with accumulated dust. Later, I learned to clean it by gently poking it with a thin needle, which was quite convenient. This small hole is designed to balance pressure inside the fuel tank, allowing air to flow in when fuel is drawn out to prevent vacuum suction issues. For maintenance, I recommend checking it every six months, especially if parked outdoors in dusty areas, as blockages can slow refueling and, in severe cases, even deform the tank. Overall, it may seem insignificant, but it can save a lot of trouble and keep the car running smoothly when it matters most.
