Gas Tank

Everything You Need to Know About Your Vehicle’s Gas Tank

Typically, the gas tank is located in a low position at the rear of the vehicle to ensure a natural flow of fuel to the engine. When fuel is used by the engine, air must enter the tank to replace the volume of fuel consumed. Additionally, modern tanks are often equipped with evaporative emission control systems that capture fuel vapors and route them to the engine for combustion, thereby reducing atmospheric emissions.

The capacity of a gas tank varies significantly depending on the type of vehicle due to their design, purpose, and performance. In general, compact cars have a gas tank capacity of around 40 to 60 liters, mid-sized vehicles have tanks ranging from 50 to 70 liters. SUVs and utility vehicles feature larger tanks, usually between 60 and 100 liters, while trucks or heavy utility vehicles often have tanks exceeding 100 liters.

Gas Tank Maintenance

Maintaining the gas tank is important to ensure the proper functioning of your vehicle and extend its lifespan. Here are some general tips to avoid gas tank repairs:

• Use high-quality fuel from reputable service stations. Avoid low-quality fuel, as it may contain impurities that damage the fuel system.
• Avoid letting the gas tank empty completely. This can help prevent the accumulation of deposits in the tank.
• Likewise, avoid overfilling the gas tank, as this may cause fuel overflow and vapor emissions.
• Ensure that the gas cap is in good condition, as a defective cap allows moisture and impurities to enter the tank.
• If your vehicle is equipped with an evaporate emission control system, ensure that it is functioning correctly. Faulty components can lead to fuel vapor leaks.
• Replace the fuel filter, as a clogged filter can reduce fuel flow and affect engine performance.
