Does a few drops of rainwater in the fuel tank matter?

If only a very small amount of rainwater enters, it will not affect usage. Below is relevant information about fuel tanks: Introduction: A fuel container on aircraft or automobiles, a fuel tank, known as a hydraulic term, is a specialized container in hydraulic systems for storing hydraulic oil or fluid. Fuel tanks can be divided into two types: open tanks and closed tanks. The bottom of the tank should be at least 150mm above the ground, and sufficient attention should be paid to the anti-corrosion treatment of the inner surface of the tank. Function: In hydraulic systems, besides storing oil, fuel tanks also serve to dissipate heat, separate air bubbles from the oil, and settle impurities. Many accessories are installed in fuel tanks, such as coolers, heaters, air filters, and liquid level gauges.
When I first started driving, I didn't tighten the fuel cap properly and a few drops of rainwater got in. To be honest, this could be a minor or major issue. Generally, rainwater and gasoline don't mix—water sinks to the bottom, and the engine is unlikely to draw it in the short term, so daily driving shouldn't be a big problem. However, don't let your guard down. Accumulated water can corrode the fuel tank, cause rust, or clog fuel lines, leading to engine stuttering or stalling, which can be especially dangerous at high speeds. A neighbor of mine once had to spend thousands on repairs because of this. I recommend tightening the cap immediately after refueling and regularly checking if the sealing ring has aged. Additionally, fuel tanks are more prone to contamination in humid environments. Taking preventive measures can save a lot of money—safe driving should always come first, so don't wait until you regret it.
