How big is the fuel tank on a 6.4 Powerstroke?

The fuel tank on a 6.4 Powerstroke diesel engine has a capacity of 38 gallons. This sizable tank allows the powerful truck to travel long distances without frequent refueling stops.


Detailed Breakdown of the 6.4 Powerstroke Fuel Tank


The 6.4 Powerstroke is a popular diesel engine found in Ford Super Duty trucks, such as the F-250 and F-350. This engine is known for its impressive towing capacity and fuel efficiency, thanks in part to its large 38-gallon fuel tank.


The 38-gallon fuel tank provides the 6.4 Powerstroke with excellent range, allowing drivers to travel up to 600 miles on a single tank of diesel fuel, depending on driving conditions and load. This is a significant advantage for those who use their trucks for hauling, towing, or long-distance travel.


Factors Affecting Fuel Tank Capacity


The fuel tank capacity of a vehicle is influenced by several factors, including the size and design of the truck, the engine displacement, and the intended use of the vehicle. Larger trucks, such as the Ford Super Duty line, typically have larger fuel tanks to accommodate their increased power and hauling requirements.


In the case of the 6.4 Powerstroke, the 38-gallon fuel tank is well-suited to the engine's performance and the needs of its target market, which includes contractors, farmers, and other users who require a powerful and capable work truck.
