What size gas tank is in the Ford f250?
Most Ford F-250 pickups with gasoline engines use a 34-gallon fuel tank. Some configurations offer an extended-range option that increases capacity to 48 gallons. Exact capacity can vary by model year, cab/bed configuration, and optional packages.
In this article, we break down the standard and optional tank sizes, explain how to confirm the capacity on your specific truck, and provide context for what the size means for range and towing.
Standard gasoline tank size
For the majority of recent Ford F-250 Super Duty models, the standard fuel tank size is 34 gallons. This capacity is typical across common engine offerings and body styles in today’s lineup, and it serves a balance of range, weight, and payload considerations.
- 34 gallons (approximately 128–129 liters) is the standard capacity listed for most gasoline-engine F-250 configurations in recent model years.
Conclusion: If your F-250 is a typical trim with a gasoline engine, expect a 34-gallon tank. Always verify the exact figure for your specific year, cab style, and bed length.
Extended-range fuel tank option
Ford has offered an extended-range fuel tank on select F-250 configurations, increasing capacity to 48 gallons to improve driving range for long trips or heavy towing. This option appears on certain trims and cab/bed combinations.
- 48 gallons (approximately 181–182 liters) is the extended-range capacity available on select configurations.
Conclusion: If your truck includes the extended-range tank, you’ll gain more miles between fill-ups; otherwise, the standard 34-gallon tank applies.
How to verify your exact capacity
Fuel capacity can vary by model year, cab style, bed length, and option packages. The most reliable way to confirm is to check the door jamb sticker on the driver's side, the window sticker when the vehicle was new, or your vehicle’s build sheet. A dealer can also pull the exact specification from the VIN and trade-in documents.
Impact on range and fueling strategy
Range depends on engine choice, payload, towing, terrain, and driving habits. With a 34-gallon tank, highway driving may yield several hundred miles of range, while towing or rough terrain reduces that figure. The 48-gallon extension lengthens range significantly on eligible builds, provided you’re not exceeding capacity through heavy towing or payload demands.
Summary
The Ford F-250’s gas tank size is typically 34 gallons for most configurations, with an optional 48-gallon extended-range tank available on select builds. Always verify the exact capacity for your year, cab/bed configuration, and package to determine your expected range and fueling needs.
