What You'll Learn

The 2021 Hyundai Accent has an 11.9-gallon fuel tank
The fuel tank in the 2021 Hyundai Accent is likely to be made of plastic, as most modern vehicles use plastic tanks that are impervious to corrosion. However, the tank combines electricity and fuel, so proper working knowledge of these components is necessary for any repairs. The fuel tank is filled with fuel through the fill spout, which connects to the fuel tank filler neck. When the tank is full, the pressure signals the fuel pump to stop sending fuel. The fuel is then sucked from the tank on demand by the fuel pump.
The fuel tank is responsible for storing engine fuel and is usually mounted to the bottom rear of the vehicle. It is part of the evaporative emissions control system and the fuel delivery system. The fuel tank pressure sensor is mounted to the top of the fuel pump assembly, which is located on top of the fuel tank. An access door to the fuel tank is located under the rear seat.
Fuel tank failure rates vary with the age of the vehicle and environmental differences. Environments with extreme temperature fluctuations, humidity, sand, salt, or deep water can impact the probability of a metal gas tank corroding. A fuel tank leak may cause difficulty starting the engine, a rough idle, and poor fuel mileage. A vehicle with a bad fuel tank should not be driven, and the fuel should be filtered before the vehicle is started again.

Fuel tank replacement costs between $1,083 and $1,420
The fuel tank in a Hyundai Accent is mounted to the bottom rear of the vehicle. It is part of the evaporative emissions control system and the fuel delivery system. Fuel tank replacement costs between $1,083 and $1,420, with labour costs estimated between $177 and $260, and parts priced between $906 and $1,160. This range does not include taxes and fees and may vary depending on your location and the specific car.
Fuel tanks are large, cumbersome, and extremely heavy, so caution must be exercised when replacing one. While a DIYer can handle the repair, an assistant is recommended to prevent injury or damage to the vehicle. Proper working knowledge of the fuel tank's components and safety procedures is essential. If you feel unqualified, it is best to leave the task to a professional technician.
Fuel tank failure rates vary with the vehicle's age and environmental differences. Extreme temperature fluctuations, humidity, sand, salt, or deep water can impact the likelihood of a metal gas tank corroding. Modern vehicles often have plastic tanks that are impervious to corrosion. However, integrated emissions components can fail and require replacement of the entire tank.
A bad fuel tank should not be driven. Corrosion, debris, and rust inside the tank can contaminate the fuel delivery system. Before starting the vehicle, the fuel must be filtered, and the fuel tank and filter replaced. A fuel tank leak can cause difficulty starting the engine, a rough idle, and poor fuel mileage. In some models, a popping sound may accompany the check engine light as the leak detection pump attempts to pressurize the fuel tank.

The fuel tank is at the bottom rear of the car
The fuel tank on a Hyundai Accent is located at the bottom rear of the car. This is the standard location for most vehicles. Fuel tanks are large, heavy, and cumbersome, so if you need to replace your fuel tank, it's best to get assistance to prevent injury or damage to the vehicle.
The fuel tank is an essential part of any vehicle, storing the engine fuel and being filled through the fill spout. The fill spout connects to the fuel tank filler neck, which has a check valve or release valve to allow fuel to enter the tank and replace the air inside. Once the tank is full, the pressure signals the fuel pump to stop sending fuel. The fuel is then sucked from the tank on demand by the fuel pump.
The fuel tank is also part of the evaporative emissions control system, which includes the EVAP system. This system is checked by closing the purge valve and vent valve and monitoring the pressure with the fuel tank pressure sensor. If the pressure drops, there is a leak in the EVAP system. The fuel tank pressure sensor is mounted to the top of the fuel pump assembly, which is located on top of the fuel tank.
Fuel tanks in the Hyundai Accent have a capacity of 11.9 gallons, with impressive fuel economy. The 2022 model can achieve an EPA-estimated 33 city and 41 highway mpg, with a combined 36 mpg. This allows for a remarkable range of around 487.9 highway miles.
Corrosion is a common issue with fuel tanks, especially in environments with extreme temperature fluctuations, humidity, sand, salt, or deep water. Modern vehicles often have plastic tanks, which are impervious to corrosion, but older vehicles with metal tanks can experience rust and corrosion over time.

A fuel tank leak may cause engine problems
The fuel tank in a Hyundai Accent is mounted to the bottom rear of the vehicle. Fuel tank leaks can be dangerous and cause engine problems. If you suspect a fuel leak, it is important to have it inspected by a professional as soon as possible.
A fuel tank leak can cause engine problems such as difficulty starting the engine, a rough idle, and poor fuel mileage. A leaking fuel line might drip onto other components under the hood or along the chassis. This can cause damage to the engine and other components. It is also a fire hazard.
There are several signs that may indicate a fuel tank leak. One of the most common signs is the smell of gasoline. A fuel leak can also cause the fuel gauge to malfunction, with the needle dropping quickly from F to E. A leaking fuel tank may also cause the check engine light to illuminate, although this can also be triggered by other issues.
Fuel tank leaks can be caused by various factors, including a damaged fuel tank or fuel lines, faulty fuel injectors, a faulty fuel filter, pressure gauge, or filler cap. The pump can also become damaged and leak gasoline into the engine compartment. Corrosion or rust inside the fuel tank can also lead to leaks.
If you experience a fuel tank leak in your Hyundai Accent, it is important to address the issue promptly. Repair costs can vary depending on the extent of the damage, but it is a complex and potentially costly repair that may require the replacement of the entire tank.

The fuel tank pressure sensor is mounted to the top of the fuel pump assembly
The fuel tank in a Hyundai Accent is located at the bottom rear of the vehicle, and it has a capacity of 11.9 gallons. The fuel tank is part of the evaporative emissions control system and the fuel delivery system. The fuel tank pressure sensor is an integral component of the fuel tank and the EVAP system. It constantly reads the pressure in the fuel tank, helping to control fuel vapour emissions.
To access the fuel tank pressure sensor on the 2015 Hyundai Accent, you need to remove the rear seat cushion to expose the access door under the rear seat. Once the access door cover is removed, you will find the fuel tank pressure sensor mounted below.
If you need to replace the fuel tank pressure sensor, you can follow these steps:
- Unplug the electrical connector from the sensor.
- Release the retainer hooks vertically.
- Pull the fuel tank pressure sensor up and off the fuel pump assembly.
The average cost for a Hyundai Accent Fuel Tank Pressure Sensor replacement is between $393 and $456, but this can vary depending on your specific vehicle. It is important to note that working on fuel systems requires proper knowledge and safety procedures. If you feel unqualified or uncomfortable performing this task, it is best to leave it to a professional technician.
