How many gallons of fuel does a F-350 hold?
The typical capacity is 34 gallons, with an optional 48-gallon tank on certain configurations to extend range.
The F-350's fuel tank size varies by year, engine choice, and cab/bed configuration. The standard 34-gallon tank is common across many trims, while the 48-gallon option is available on select diesel builds and specific cab/bed layouts. For the exact figure on a given truck, check the window sticker, dealership specs, or the vehicle's VIN-to-spec sheet.
Fuel Tank Capacities by Configuration
Below is a quick guide to typical capacities you might see on current Ford F-350 Super Duty trucks. The numbers can vary with year and configuration, so use this as a reference rather than a guarantee.
- Gasoline-powered F-350: typically 34 gallons.
- Diesel-powered F-350: typically 34 gallons; 48 gallons available as an optional long-range tank in select configurations.
Keep in mind that payload and drivetrain options can influence tank size in certain trims. The 48-gallon tank is designed to improve range on longer trips or heavy-haul work.
Verifying your exact capacity
Because Ford offers multiple tank sizes across years and trims, the most reliable way to know your truck’s capacity is to consult the window sticker, owner's manual, or dealer records. The VIN can also be used to pull the precise specification from Ford’s database.
Why tank size matters for range
Fuel tank capacity directly affects how far you can travel between fill-ups, particularly when towing heavy loads or traveling in areas with fewer refueling options. A larger 48-gallon tank can add hundreds of miles of range under typical highway conditions, while a standard 34-gallon tank remains sufficient for most daily tasks.
Summary
In practice, the Ford F-350's fuel capacity is not fixed; it depends on the year, engine, and configuration. The most common figure is 34 gallons, with an optional 48-gallon long-range tank available on select builds. For precise capacity, verify your specific vehicle’s documentation or VIN data.
