Symptoms of a Bad or Faulty Fuel Filler

Common signs include the smell of fuel coming from the vehicle, the Check Engine light coming on, and fuel leaks.

The fuel filler neck is an important but often overlooked component of the fuel system. The fuel filler neck is the component that connects the fuel filler neck to the fuel tank and provides a path for fuel to enter the tank as it fills up. Fuel fillers are usually made of metal or rubber, which, while durable, can wear out over time. A bad or faulty fuel filler can cause vehicle emissions problems and can even be a safety hazard if the vehicle leaks fuel. Usually, a defective or defective fuel filler neck causes several symptoms that can alert the driver to a potential problem.

1. The smell of fuel

One of the first symptoms usually associated with a bad or faulty fuel filler neck is the smell of fuel. While it's normal to have a slight fuel smell when refueling, if the smell persists or gets stronger over time, it could be a sign that the fuel filler neck may have a slight leak. In addition to the smell of fuel, a fuel filler leaking fumes can also cause problems with a vehicle's EVAP system.

2. Check Engine light comes on.

Another sign of a possible fuel filler problem is a glowing Check Engine light. If the computer detects any problem with the vehicle's EVAP system, it will turn on the Check Engine light to notify the driver of the problem. The EVAP system is designed to capture and reuse vapors from the fuel tank and will illuminate the Check Engine light if there is any leakage in the fuel tank, neck, or any of the system hoses. The Check Engine light can also be caused by a variety of other issues, so it is highly recommended that you scan your computer for trouble codes.

3. Fuel leaks

Another sign of a fuel filler problem is a fuel leak. If any fuel leakage occurs from the side of the vehicle where the filler neck is located, especially while refueling the vehicle, this could be a sign of a potential problem with the vehicle's filler neck. Most fillers are made of rubber or metal, which can corrode and wear over time, and leak fuel. Any fuel leaks should be repaired as soon as possible as they can quickly develop into a potential safety hazard.

While replacing the filler neck is not necessarily a routine maintenance procedure, it is an important job because the filler neck plays an important role in a vehicle's fuel system. If there is a problem with your vehicle's filler neck, have your vehicle checked by a professional technician such as AvtoTachki to determine if the filler should be replaced.
