What Causes Gasoline Leakage in Cars?

Gasoline leakage in cars usually occurs when a 4S shop replaces the fuel filter for the vehicle. Since the fuel filter is located on the chassis, if some pipelines are not properly connected during replacement, it can lead to oil leakage. Alternatively, after refueling, if the seal ring of the fuel pump in the fuel tank is not installed properly, oil leakage may occur when encountering poor road conditions. Below are specific details on carburetor maintenance: Cleaning the carburetor and fuel injector: Mainly involves cleaning the idle valve and filter screen. These cleaning tasks should be performed at a formal maintenance and repair center, as roadside repair shops lack the necessary professional equipment, and random cleaning may not yield any benefits. Carburetor cleaning should be conducted in a clean area: The outer surface of the carburetor should be wiped clean, and internal parts can be cleaned using carburetor-specific cleaner or industrial gasoline. In addition to removing impurities, attention should be paid to cleaning gasoline residues on the surface of the parts. After cleaning, the parts should be blown dry with compressed air. Avoid using cloth or paper that may produce burrs to prevent recontamination.

I remember one time when I was driving out, I suddenly smelled a strong gasoline odor, which really scared me. I quickly pulled over to check and found oil dripping under the car. This is extremely dangerous—gasoline is highly flammable and explosive. If it comes into contact with a spark, the car could catch fire and also pollute the environment. Common causes include aging and cracked fuel lines, worn seals on the fuel pump, or holes in the fuel tank. When I later asked at a repair shop, minor issues like hose replacements could be fixed for a few hundred bucks, but ignoring them could lead to a major fire. So if you notice a fuel leak, immediately turn off the engine, avoid lighting anything or smoking, and call a tow truck to take it to a professional. Safety first—don’t cut corners to save money; lives are at stake.

Last summer, my vintage car leaked oil on the highway, leaving oil stains all over the parking spot. After checking, it turned out the fuel tank connection was loose, causing oil to seep out over time. That experience taught me a lesson: always glance under the car or around the wheel arches before driving each day to check for oil traces; be alert if you smell anything unusual. There are various reasons for gasoline leaks—faulty fuel pumps, loose fuel caps, or aging filters could all be culprits. Ignoring it long-term not only wastes fuel costs but also shortens the car's lifespan. I recommend regular maintenance, such as having a technician inspect the fuel system components every six months, and parking on smooth surfaces to avoid damaging the fuel tank. This way, you save both hassle and effort.
