How many gallons does a Ford e450 hold?

The Ford E-450's fuel capacity is not fixed; most standard configurations use a 35-gallon tank, with some options offering 40 gallons. The exact capacity depends on year, engine, and body configuration.


Typical capacities by configuration


Here are the common fuel-tank capacities you may encounter on Ford E-450 cutaway models.



  • Standard tank: 35 gallons (about 132.5 liters).

  • Extended-range option: 40 gallons (about 151 liters) on certain configurations.

  • Conversion-specific or aftermarket tanks: Some builds may use different sizes; verify for your exact vehicle.


In practice, the majority of E-450s use the 35-gallon tank, with 40 gallons appearing in limited configurations or as an option.


How to confirm the exact capacity for your vehicle


To be precise about your specific E-450, check the official specifications for your year and body type and look for the fuel-capacity information on the vehicle.



  • Check the fuel-capacity label on the fuel filler area or the driver's door jamb—the label lists the gallons capacity.

  • Consult the owner's manual or Ford's official spec sheets for your year and body configuration (cutaway, shuttle, ambulance, etc.).

  • If you have a custom conversion, locate the build sheet or contact the converter or dealer with your VIN to confirm the tank size.

  • If necessary, contact a Ford dealer with your VIN to retrieve the exact specification from the factory data.


Exact capacity varies by configuration; the steps above will give you the precise figure for your specific E-450.


Why the fuel capacity matters


Fuel capacity affects range, fueling logistics, and maintenance planning—issues that matter for fleets, shuttle services, ambulances, and RV conversions where predictable range is essential.


Summary: The standard Ford E-450 fuel tank is typically 35 gallons, with 40 gallons available in some configurations. Always verify the exact capacity for your vehicle using the label, manual, or VIN-based specifications.
