Big truck fuel tank sizes in our inventory typically range from 300 to 600 liters for standard long-haul tractors, with auxiliary tanks available to extend capacity up to 1,000 liters. The Dongfeng 13L tractor, for example, is equipped with a 400L main fuel tank that provides a driving range of approximately 1,200 km under normal operating conditions. For long-haul applications requiring extended range, an optional 200L auxiliary tank can be integrated, increasing total capacity to 600L and extending the range to 1,800 km. Diesel-powered construction trucks often feature 350L tanks to balance fuel efficiency with the need for frequent stops at job sites. Tank materials include high-grade stainless steel or carbon steel with anti-corrosion coatings, and all tanks are equipped with fuel level sensors, vapor recovery systems, and crash-resistant baffles to prevent fuel surge. Contact our fuel system specialists for detailed tank specifications, including dimensions, mounting configurations, and compatibility with alternative fuels like biodiesel (up to B20 blend).
