Car Leaking Fuel: Causes and Fixes
Fuel leaking from a car is an issue that requires immediate attention. Not only does it pose the risk of running out of fuel but this is also harmful for the environment. It is therefore important for every vehicle owner to know the symptoms and causes of fuel leaks in a car to address this issue promptly. We will take a look at the common causes of fuel leaks in a car, the symptoms and the ways to fix this problem.
Fuel Leaks in Car Symptoms
Leakages of any type can have devastating effects on the vehicle. For instance, engine oil leaks can lead to engine overheating or worse. Similarly, petrol leakage can leave a vehicle stranded. Moreover, it can pose a threat to other vehicles on the road.
Listed below are the symptoms of a fuel leak in a car to be aware of.
- Strong petrol odour around the vehicle.
- Puddles of petrol under the car, when parked.
- Check the engine light or EVAP warning light illuminated on the dashboard.
- Decreased fuel efficiency or engine sputtering.
Causes & Fixes of Fuel Leaks in Cars
Petrol leakages can be caused by damage to some car engine parts or external components. Let’s take a look at what causes fuel leaks in cars and how to fix the issues.
Worn-out or Damaged Fuel Tank
The most common reason behind fuel leaks is a worn or damaged fuel tank. Over time, exposure to the elements or physical damage can cause cracks and holes in the tank, allowing fuel to escape.
If there’s a suspicion of fuel tank leakage, have it inspected by a professional mechanic to assess the damage and recommend repairs or replacement. Moreover, regular inspections can help identify issues before they become severe.
Faulty Fuel Lines
Fuel lines transport petrol from the tank to the engine. If these lines become cracked or corroded, they can leak fuel either onto the ground or into the engine compartment.
Carry out a vehicle inspection to identify faulty fuel lines. If the inspection reveals cracked or corroded fuel lines, replace them immediately to prevent further leakage. Additionally, it is important to inspect fuel lines regularly for signs of wear.
Bad Petrol Cap
A loose or damaged petrol cap is also one of the causes of fuel leaks in cars. If the cap fails to seal properly, it can allow vapours and liquid fuel to escape.
Be wary of the symptoms of a bad fuel cap to avoid escalation of the issue. Ensure the petrol cap is properly tightened. However, if it’s damaged, replace it with a new one to prevent vapour escape.
Damaged Fuel Pump
The fuel pump draws petrol from the tank and sends it to the engine. A damaged pump can leak fuel, creating a fire hazard and damaging other engine components.
Have the fuel pump examined by a mechanic who can determine if it needs repair or replacement. Moreover, regular maintenance checks on the fuel pump are advisable.
Fuel Pressure Sensor Issues
The fuel pressure sensor monitors the pressure within the fuel system. If it malfunctions, it may lead to an overflow situation, causing fuel to leak out.
Know the symptoms of a bad fuel pressure sensor and take the vehicle to a professional as soon as possible. Depending on the nature of the damage, the mechanic will repair or replace the sensor.
Purge Control Valve Issues
This valve controls how much fuel vapours are released into the engine for combustion. A failing purge valve can send excess vapours into the system, resulting in noticeable leaks.
A malfunctioning purge valve should be replaced promptly to maintain proper vapour control in the vehicle’s system.
FAQs
How to Prevent Fuel Leak in Car?
To prevent petrol leaks in your car, regularly inspect and maintain essential components like fuel lines, injectors and the fuel cap. Also, avoid overfilling the fuel tank to prevent excess pressure that can lead to leaks.
Is it Safe to Drive a Car With a Fuel Leak?
Driving a car with a fuel leak is not safe. It poses a significant risk of fire and can lead to further damage to the vehicle.
Is a Fuel Leak an Easy Fix?
A fuel leak can be an easy fix if it involves minor issues like a worn hose or a faulty petrol cap. However, more severe leaks, such as those requiring tank replacement or extensive repairs, can be complex and costly. Be wary of the issues related to all the components. For instance, fuel tank not filling or sensor issues among more and fix them at the earliest.
These are all the symptoms and causes of vehicle fuel leakage. The aforementioned fuel leak fixes in a car can help vehicle owners avoid further damage.
