What You'll Learn
Fuel line malfunctions and damage
Wear and Tear
Fuel lines, like any other component in an engine, are susceptible to wear and tear over time. Even with the best fuel quality, gunk can accumulate in fuel lines due to engine debris or imperfections in the fuel. This buildup can lead to clogging, reducing or blocking the fuel flow to the engine.
Sudden Impact Damage
In some cases, fuel lines may sustain damage from sudden impacts or blunt force. For example, high-centering a vehicle has been known to cause damage to fuel lines. Similarly, running over a curb can result in scraping the bottom of the car, disconnecting linkages and cables, and damaging transmission fluid and cooling lines. While there is no definite evidence that it can break a fuel line, the impact of going over a curb could potentially lead to fuel line damage.
Symptoms of Malfunction
A malfunctioning fuel line will exhibit symptoms such as a lack of fuel flow or inconsistent fuel supply to the engine. This can cause the engine to sputter or die, and in some cases, the vehicle may not start at all. Smoke in the engine compartment is another dangerous sign of a faulty fuel line, as leaking fuel can come into contact with heat sources and ignite.
Safety Hazards
Defective fuel lines pose serious safety risks. Leaking fuel can create hazardous smoke, making it challenging to drive safely. Additionally, the highly flammable gasoline escaping from a damaged fuel line can lead to fires or even explosions in the engine compartment.
Maintenance and Repair
To avoid fuel line malfunctions and potential safety hazards, regular maintenance and replacement of fuel lines are crucial. While it may be costly to repair or replace a fuel pump or fuel lines, it is essential for the vehicle's performance and your safety. If you suspect any issues with your fuel lines, it is recommended to have them inspected and serviced by a qualified mechanic as soon as possible.

Fuel line leaks and fire hazards
Fuel line leaks can have serious consequences, including fire hazards. The fuel line is responsible for transmitting fuel to power a vehicle, and when it malfunctions, it can lead to a lack of fuel flow or inconsistent fuel supply to the engine. This can cause issues such as engine stalling, misfires, and delays. A damaged fuel line can also allow too much air into the engine's combustion chamber, leading to overheating and potential engine damage.
Visible fuel leaks are a clear sign of a problem and can be detected by inspecting for puddles of fuel underneath the car. Leaks can also occur internally, with fuel escaping into the interior of the car. This is particularly dangerous as it releases carbon monoxide, which is harmful to health. The strong smell of gasoline inside the car is an indication of this type of leak and should be treated as urgent. Passengers may experience headaches and nausea due to the inhalation of gasoline fumes, and there is also a risk of fire if the fumes come into contact with a heat source.
To prevent fuel line leaks and the associated fire hazards, regular inspections of the fuel line are crucial. Look for cracks, wear, or damage along the entire length of the fuel line, especially at connections and junctions where leaks are more common. Corrosion, particularly in older vehicles or those exposed to harsh environments, is a common cause of fuel line damage. If you suspect an issue, a pressure test can be performed to confirm the integrity of the fuel line.
If a fuel line leak is suspected or detected, it is important to take the vehicle to a mechanic as soon as possible. While fuel line repair or replacement is usually not an expensive job, ignoring the problem can lead to further deterioration and serious engine issues. A hissing sound, similar to a tire releasing air, may also indicate a leaking fuel line, as well as a sudden decrease in fuel efficiency.

Fuel line repair costs
Fuel lines are liable to break over years of wear and tear, or they may be damaged by spontaneous events, such as blunt force. Faulty fuel lines can cause fuel to spray or leak out, and fuel that comes into contact with a heat source may ignite. Therefore, it is important to get them repaired as soon as possible.
The cost of repairing or replacing a fuel line varies depending on the extent of the damage and the make of the car. On average, you can expect to pay between $300 and $500, including parts and labour, for a basic fuel line repair. However, if the existing fuel lines are in poor condition or require the shop to remove the gas tank, the price can increase significantly, sometimes costing $1,000 or more. For example, one person was quoted $1,500 to cut out and replace the rusted section of the fuel line, as well as the most rusted parts of the lines further up the car. Another person was quoted $3,000 to replace the entire fuel line of their 1999 Olds Cutlass.
If you are thinking of repairing the fuel line yourself, you can buy fuel line sets for less than $200, and there are instructions and videos online that can help you with the process. However, it is important to remember that poor-quality fuel lines will corrode and wear out faster, costing you more money in the long run.
To save money, it is recommended to find a good independent repair shop to do the work, as dealerships will often charge more. It is also a good idea to check the shop's ratings and customer reviews, as well as verify that the shop is AAA-approved or staffed with ASE-certified mechanics.

Car damage from hitting a curb
Hitting a curb with your car can cause a variety of issues and damage, some of which may be difficult to identify without an expert assessment. The speed of the impact and the height of the curb will affect the extent of the damage. Even a slight jolt can cause problems with your transmission case, linkages, cables, transmission fluid and cooling lines, oil pan, and valve.
One of the most common issues resulting from hitting a curb is damage to your car's suspension system. The suspension is a complex system with many parts that can be easily damaged, even at slow speeds. A damaged suspension will cause a bouncy feeling when driving, especially over bumps or potholes. A broken suspension arm may cause your vehicle to slam down forcibly when it encounters a bump. A common symptom of suspension damage is a drifting or pulling feeling to one side. This can also be caused by damage to the wheel bearings, which can make steering feel wobbly and difficult to control.
Damage to the wheel rims and wheel bearings can also cause steering issues, including imprecise steering and loose steering. Bent rims can cause the steering wheel to wobble, and a damaged wheel bearing may create a grinding noise.
Tires can also be damaged by hitting a curb, with possible pinching of the rubber or scraping of the sidewall. More serious damage could include tears or punctures, which may require patching or replacement.
Hitting a curb can also damage the car's exhaust system, including the muffler, hangers, brackets, and, in severe cases, the catalytic converter. The muffler is the most likely part to be damaged, and you may hear excessively loud exhaust sounds or rattling as a result.
In rare cases, a fuel line may be damaged by hitting a curb, although this is more likely to occur due to wear and tear or blunt force from high-centering the vehicle. A damaged fuel line may cause engine issues, including sputtering or dying, and you may notice smoke in the engine compartment.

Car suspension and control issues
Hitting a curb can cause serious damage to your car, and it's important to get it checked out by a professional as soon as possible. While fuel lines are unlikely to break from going over a curb, other issues can arise that affect the suspension and control of your vehicle.
The suspension of your car is designed to provide a smooth ride and absorb impacts from the road. If you've hit a curb, the suspension may have taken a knock, and you might experience a bumpy ride. A broken suspension arm can cause your car to slam down when you hit a bump, and you may feel like you're on a roller coaster. This can be quite a jarring experience and indicates a suspension inspection is needed. Bad suspension problems will only worsen over time, so it's important to address them promptly.
Curbs can also damage car tie rods, which are critical connections between your steering column, driveshaft, and wheels. Broken tie rods reduce your ability to control the car, especially during turns. In addition, sway bars, which are essential for stability when turning, can be affected by a curb impact. If your steering wheel is crooked or not straight when driving in a straight line, this could be an indication of sway bar damage.
While fuel line damage from a curb is less likely, it's important to be aware of the dangers of defective fuel lines. A fuel line malfunction can occur due to wear and tear or spontaneous damage. This can result in a lack of fuel flow or inconsistent fuel supply to your engine, causing it to sputter or even stop working. A clogged fuel line is another possibility, often caused by the buildup of gunk or engine debris over time. Defective fuel lines can lead to fuel leaks, which, in combination with a heat source, pose a serious fire risk. Given the potential safety implications, it's crucial to have your fuel lines checked and replaced if necessary.
