How to make a hole in the motorcycle fuel tank without ventilation? Be specific.

Motorcycle fuel tank is not ventilated, mostly because of the problem of fuel tank cover, which is more common in newly bought cars. Because the fuel tank cover is closed too tightly, it will naturally improve with use. If the situation is serious, you can also try to change a slightly thinner tank cover pad, or deal with the tank cover and the tank cover opening as appropriate. It is best not to punch holes easily. If a hole is to be punched, it is usually in the corresponding position on the can cover, depending on the specific situation.
