Kenworth fuel tank capacities range from 60 to 150 gallons
Some Kenworth trucks have dual fuel tanks, which means they have two tanks that work together to provide fuel to the engine. The total capacity of the fuel system in these trucks is the combined capacity of both tanks. For example, a 2019 Kenworth T680 may have twin 75-gallon fuel tanks, resulting in a total capacity of 150 gallons.
Upgrading to an aftermarket fuel tank can provide a larger fuel capacity, which can be beneficial for long-haul trips by reducing downtime and saving costs. Aftermarket fuel tanks for Kenworth trucks are available in various capacities, ranging from 60 gallons to 150 gallons. These tanks are made of heavy-duty aluminum or steel and offer versatility in terms of mounting location (front, side, or rear) and filling options (front fill, rear fill, or side fill).
Kenworth fuel tanks are also available in different materials, such as mirror-finish polished aluminum and durable steel, to meet aesthetic preferences and performance requirements. Some fuel tanks are designed for specific Kenworth models, such as the Kenworth W900, T800, T880, and W990, to ensure a precise fit and optimal performance.
It is important to note that the fuel tank capacity of a Kenworth truck can vary, and it is always recommended to refer to the specific model's specifications for accurate information.
