What are the symptoms of water in the fuel tank?

[ODerek]

When there is water in the fuel tank, the car may experience difficulties in starting, engine shaking, backfiring, high idle speed, or insufficient power. Water in the fuel tank can also cause rust, corrosion, and blockage in the fuel tank and fuel lines, affecting the normal fuel supply of the fuel system. This can lead to poor combustion, unstable idle speed, and poor acceleration. The presence of water in gasoline can cause rust on the inner walls of the metal fuel tank. When rust particles adhere to the fuel pump's filter screen, the resistance to fuel suction increases, resulting in insufficient fuel supply to the engine and reduced power. Over time, the fuel pump may fail. Gasoline is prone to mixing with water during production, storage, and transportation, especially in large oil tanks where the gasoline at the bottom tends to have higher water content.
