How many gallons does an E450 hold?

The Ford E-450’s fuel capacity is typically around 35 gallons in its standard configuration, but actual capacity varies by model year, engine, and body setup. Some RV and heavy-duty builds use larger tanks, up to about 55 gallons.


Understanding the E-450 and its fuel capacity


The E-450 is Ford’s full-size, heavy-duty cutaway/van chassis used for a range of applications—from shuttle vans and ambulances to recreational vehicles. Because the chassis serves multiple markets, the fuel-tank size is not fixed and depends on the specific build and equipment installed.


Typical capacity by configuration


Below are the common ranges you may encounter in contemporary E-450 builds. The exact figure for a given vehicle is listed on the fuel-tank label near the fuel filler or on the build sheet.



  • Standard tank: 35 gallons on most E-450 vans and cutaways with the common gasoline engine.

  • Extended tanks: Some RV and heavy-duty configurations use larger tanks, typically in the 40–55 gallon range.

  • Special cases: A few fleets or conversions may have customized tanks; verify with the VIN or build documentation.


Concluding: While 35 gallons serves as the common baseline for many E-450 models, the actual capacity can be larger in extended or specialized builds, so always confirm with your specific vehicle’s documentation.


How to verify your specific E-450


To determine the exact capacity for your unit, check the driver-side door jamb fuel label, consult the owner's manual, review the original build sheet, or contact the dealer or manufacturer using the VIN. This ensures you have the precise figure for planning fuel stops and range.


Why capacity varies


Factors include engine type (gasoline V10 or other options across years), body configuration (cargo, passenger, ambulance, or RV cutaway), and whether an extended or auxiliary tank was installed.


Summary: The E-450’s fuel capacity is not fixed; most commonly it holds about 35 gallons, with larger tanks available in certain RV and heavy-duty configurations (up to around 55 gallons). Always verify the exact capacity from your vehicle’s official documentation for accurate planning.
