The fuel tank cap connecting wire needs to be replaced if it's broken. Below are the functions of the fuel tank cap drain hole: 1. Facilitate drainage: There is a drain hole under the fuel tank cap, usually located on the inclined surface of the fuel tank opening. Its primary purpose is to facilitate drainage, as accumulated water could easily flow into the fuel tank, potentially contaminating the gasoline. 2. Protect the engine: Accumulated water can cause significant damage to the car's engine, so the drain hole plays a crucial protective role, extending the engine's lifespan.
