What is the problem with gasoline leaking under the car?

Here is an introduction to oil leakage from the car chassis: 1. Shock absorber oil leakage. Generally, shock absorber oil leakage is easy to detect and has no repair value, so it should be directly replaced with new equipment. 2. Brake master cylinder, wheel cylinder, or ABS pump oil leakage. When removing or installing oil pipe screws, it is best to use a special oil pipe wrench and tighten them according to the standard torque. 3. Clutch master cylinder or wheel cylinder oil leakage. The clutch master cylinder and wheel cylinder are very similar in appearance to the brake master cylinder, but there is only one outgoing oil pipe. Generally, they are replaced due to piston oil leakage. 4. Half-shaft oil seal leakage. 5. Rear differential oil seal leakage. The rear axle differential oil seal is easier to replace than the front-wheel-drive oil seal. Simply remove the drive shaft for replacement, without the need for sealing adhesive. Press it in at both ends and flatten it. 6. Transmission oil pan leakage. If there is oil leakage at the automatic transmission oil pan, the sealing gasket needs to be replaced, and new ATF should be added, along with replacing the filter. When installing the oil pan, the old sealing adhesive must be completely cleaned off, and the new sealing adhesive should be applied evenly, especially at the corners. Bolts should be tightened according to the standard torque, starting from the middle and then moving to both sides.

Having driven for decades, when I notice gasoline leaking under the car, my first instinct is to check the fuel tank and its connections, as the bottom of an old vehicle's tank may rust through, and fuel line fittings could be loose or worn out. Sometimes, leaks occur simply because the gas cap wasn't tightened properly after refueling. Then, I consider whether the fuel pump or filter seals might be damaged, as leaks from these areas are quite common. Additionally, if the car has been in an accident recently, impact could have cracked the fuel lines. Gasoline leaks are extremely hazardous—just a spark can cause a fire, and they also pollute the soil. That's why upon discovering a leak, it's crucial to stop immediately and arrange for a tow to the repair shop—don't risk driving until it ignites. During routine maintenance, I always recommend cleaning the undercarriage and inspecting fuel lines, especially in humid areas where corrosion accelerates. Spending a little extra effort on prevention can save a lot of trouble down the road.

When I first started learning to drive, I encountered gasoline leaking from under the car, which scared me out of my wits. I thought it might be due to a loose cheap fuel tank plug or worn-out pipes; misfilling gasoline could also cause splashing, but continuous leakage under the car is a serious issue. The aging of the filter seal is the most common cause of oil leaks, especially in older cars. Gasoline is highly flammable—just a spark could set the underside of the car on fire, how dangerous! I immediately turned off the engine and called a tow truck to take it to the repair shop. The mechanic said it was a simple fix of replacing a gasket, costing only around a hundred bucks. I suggest everyone take a closer look at the chassis during each maintenance check—don’t be like me, trying to save small money but risking big trouble. If you smell a strong gasoline odor, investigate immediately; saving money shouldn’t come at the cost of safety.

Whenever I smell gasoline and notice oil leaking under the car, I immediately recognize it as a danger signal, as leaks often originate from a punctured fuel tank or aged fuel line connections; impacts can also crack components. Gasoline is highly volatile and can explode upon ignition, posing a life-threatening risk. Stop the car immediately to inspect but avoid touching the leak to prevent sparks; call emergency services for towing and repairs. Replacing a fuel tank or lines isn't costly, but the hidden danger can be fatal—never risk continuing to drive.
