How many gallons of diesel does a F-450 hold?
In standard form, a Ford F-450 Super Duty diesel typically carries 34 gallons of fuel, with an optional extended-range tank bringing the total to 48 gallons on select configurations. This means most trucks start with 34 gallons, while certain builds offer up to 48 gallons for longer runs between fills.
Standard tank capacity
The baseline diesel fuel tank on most Ford F-450 models equipped with the 6.7-liter Power Stroke engine is 34 gallons. This size is common across many heavy-duty Ford Super Duties and provides a balanced combination of payload, space, and weight for daily use and towing.
Before outlining any variations, it’s important to understand the typical size most owners will encounter.
Here are the common configurations you may encounter:
- Standard diesel tank: 34 gallons
- Optional extended-range tank: 48 gallons
In practice, many buyers may see the 34-gallon tank as the default, while the 48-gallon option is available on specific trims or as an accessory package in certain model years. Always verify your vehicle’s exact capacity on the window sticker or via Ford’s official spec sheets for your year and trim.
What changes with the extended-range option
The 48-gallon Extended Range Fuel Tank increases the diesel capacity by roughly 14 gallons, which can substantially extend driving range between fills, especially for long highway workloads or heavy towing. This option is not universal and is typically tied to particular trim levels, bed configurations, or regional availability.
How to confirm your truck’s tank size
To confirm the exact tank size for your F-450, check the window sticker on the vehicle, consult the owner’s manual, or contact a Ford dealer with the specific year, trim level, and drivetrain configuration. Vehicle specifications can vary by year and by optional equipment.
Bottom line
Most Ford F-450 diesels use a 34-gallon tank, with an optional 48-gallon extended-range tank available on select configurations. Always verify the precise capacity for your particular truck to determine expected range and fueling needs.
Summary: The fenced-in baseline is 34 gallons, with up to 48 gallons possible on certain F-450 configurations. Your exact figure depends on the year, trim, and whether the extended-range tank is installed. For the most accurate answer, check the window sticker or dealer specification for your specific vehicle.
