Ford F250 Fuel Tank Size Chart by Year

This table summarizes factory-equipped, US-market F-250 Super Duty pickups, not F-250 light-duty variants, stripped chassis-cabs, or trucks with aftermarket replacement or auxiliary tanks. A slash means that more than one factory capacity existed for the model year; use the configuration sections below to choose the correct figure.

Reading the chart: These are advertised nominal capacities, not the number of gallons you should expect to pump at every fill-up. In particular, a 2016 diesel Regular Cab with an 8-foot box does not automatically get the 37.5-gallon tank. Its shorter wheelbase puts it in the 26-gallon group.

What Fuel Tank Size Does a 2026 F250 Have

Ford offers the 2026 F-250 with a 6.8L gasoline V8, a 7.3L gasoline V8, and standard-output or high-output 6.7L Power Stroke V8 Turbo Diesel engines. For tank size, the two gas engines share the same specifications, as do the two diesel versions.

SuperCab, 147.9-inch wheelbase34 gal29 gal
SuperCab, 164.1-inch wheelbase34 gal34 gal
Crew Cab, 159.7-inch wheelbase34 gal34 gal
Crew Cab, 175.9-inch wheelbase48 gal48 gal

These figures come from Ford’s official 2026 Super Duty pickup technical specifications, page 4.

The key distinction is wheelbase, which is the distance between the centers of the front and rear axles. A diesel Regular Cab and a long-wheelbase diesel Crew Cab can have very different tank capacities despite using the same 6.7L engine.

How F250 Fuel Tank Sizes Changed From 1999 to 2016

Ford changed its tank specifications several times before the larger 48-gallon pickup tank appeared in the redesigned 2017 Super Duty. The differences are small in some years and substantial in others.

Early Super Duty Fuel Tanks From 1999 to 2004

For these years, Ford’s pickup refill-capacity tables show 29 gallons for the short box and 38 gallons for the long box. The 1999 documentation includes specific body-configuration descriptions, so confirm that you are reading the pickup entry rather than a separate chassis-cab fuel-tank listing.

The 2004 F-250 owner’s guide lists the two pickup capacities together. Its separate 19-, 23-, and 40-gallon entries are for other fuel-tank arrangements, including chassis-cab applications. They should not be added to the pickup’s capacity.

Short Bed Changes From 2005 to 2010

For 2005–2007, Ford lists 30.5 gallons for the short box and 38 gallons for the long box. The 2005, 2006, and 2007 owner’s guides agree on these figures.

The 2008–2010 guides instead specify 30.0 gallons for the short box and 38 gallons for the long box. Ford’s 2010 F-250 owner’s guide, in its maintenance and specifications section, confirms the 30.0- and 38.0-gallon figures. Do not round 30.5 into 30 or treat the two model-year groups as interchangeable.

Gas and Diesel Differences From 2011 to 2016

The 2011 redesign changed the capacity pattern. The gasoline-engine pickup used a 35-gallon tank, while the 6.7L Power Stroke V8 Turbo Diesel used 26- or 37.5-gallon tanks according to wheelbase.

Ford’s 2011 Super Duty brochure identifies 26 gallons for diesel trucks with 137-, 142-, and 156-inch wheelbases and 37.5 gallons for the 158- and 172-inch diesel wheelbases. The 2016 product specifications retain that capacity pattern.

Do not assume that every long-bed diesel holds 37.5 gallons. The Regular Cab long-bed wheelbase falls into the 26-gallon group. Engine type, cab, and wheelbase matter more than the bed label alone.

Why 2017 to 2026 F250 Tanks Depend on Wheelbase

The 2017 redesign introduced a larger factory tank for the longest pickup configuration. Across the 2017–2026 era, the standard gasoline pickup choices are 34 and 48 gallons, while diesel pickup configurations can use 29, 34, or 48 gallons.

The 29-gallon diesel tank is associated with the approximately 142- and 148-inch wheelbases. Trucks around 160 and 164 inches use the 34-gallon diesel tank; the approximately 176-inch wheelbase uses the 48-gallon tank. Gasoline pickups use 34 gallons except for the 176-inch wheelbase, which uses 48 gallons.

The large-capacity version is typically the Crew Cab with the 8-foot box. A SuperCab with an 8-foot box is a different wheelbase and should not be assigned 48 gallons simply because it has a long bed.

Why F250 Cab and Bed Length Affect Fuel Capacity

The F-250 has three main cab styles: Regular Cab, SuperCab, and Crew Cab. Its pickup boxes are commonly described as 6.75-foot short beds and 8-foot long beds. The available cab-and-box combinations change the distance between the axles and the space available for the fuel tank.

For the actual cab-and-box combinations, see the Ford F250 bed size chart by year. That page covers box measurements; this one covers fuel capacity.

If you are checking a replacement tank, match the year, engine, wheelbase, tank location, and original equipment. Bed length is a useful clue, but it cannot replace an exact fitment check.

How to Verify Your F250 Fuel Tank Capacity

Use this process when the chart gives more than one capacity for your model year.

  1. Confirm your model year. Use the vehicle registration or identification records to distinguish, for example, a 2016 from a 2017 Super Duty.
  2. Identify the engine. Check whether the truck has a gasoline V8 or a Power Stroke diesel. This matters especially for 2011 and newer trucks.
  3. Check the cab and box. Record whether it is a Regular Cab, SuperCab, or Crew Cab, then note the short or long pickup box.
  4. Confirm the wheelbase. Consult the correct model-year Ford technical specification or original vehicle build records. Measure from the center of the front wheel to the center of the rear wheel if documentation is unavailable and the truck can be measured safely on level ground.
  5. Check for modifications. An aftermarket replacement, auxiliary, or larger-capacity tank can make the factory chart inapplicable. Check installation records or have a qualified shop identify the fitted tank.

A VIN helps a dealer retrieve build information, but the VIN characters alone are not a universal fuel-tank-capacity decoder. Confirm the exact tank from the factory build record and physical equipment where necessary. Never disconnect a fuel line or remove a tank merely to estimate capacity.

How F250 Fuel Tank Size Affects Driving Range

A bigger tank can increase the distance between stops, but it does not change the truck’s fuel consumption. An easy estimate uses the truck’s measured miles per gallon, not an assumed economy rating.

Theoretical driving range = tank capacity × observed MPG.

For example, at a hypothetical 12 MPG, a 29-gallon tank gives 348 miles, a 34-gallon tank gives 408 miles, and a 48-gallon tank gives 576 miles. These are mathematical examples, not tested F-250 fuel-economy figures or safe distances to drive before refueling.

Real range changes with towing weight, speed, grade, idling, temperature, and available reserve. If towing is part of your setup, compare the appropriate configuration in the 2024 Ford F-250 towing capacity chart rather than assuming every F-250 behaves alike.

Why Your F250 Takes Fewer Gallons at the Pump

The manufacturer’s advertised tank capacity is not necessarily the number of gallons you can add when the gauge reads empty. Ford explains that fuel remains in an empty reserve, and the amount is not specified as a fixed usable driving allowance.

That is why a nominal 34-gallon tank may accept less than 34 gallons during an ordinary refill. An early pump shutoff, the starting fuel level, or filling conditions can also affect the amount added.

Do not deliberately drive until the engine runs out of fuel to test the tank. Use the owner’s manual and factory configuration instead of measuring capacity by a single fill-up.

Which Ford F250 Fuel Tank Size Should You Use

The Ford F250 fuel tank size chart provides the factory starting point, but the right answer is tied to year, engine, cab, and wheelbase. The distinctions are particularly important for 2011–2016 diesels and 2017–2026 trucks with three different diesel capacities.

Check your truck’s original documentation before ordering fuel-system parts or estimating fuel-stop intervals. For related truck specifications, the broader Ford towing capacity chart explains how model and configuration affect towing ratings, which should be checked separately from tank size.

Ford F250 Fuel Tank Size FAQs

How Many Gallons Does a Ford F250 Hold?

For 1999–2026 Super Duty pickups, documented factory tank sizes include 26, 29, 30, 30.5, 34, 35, 37.5, 38, and 48 US gallons. The correct capacity depends on the model year and configuration, not the F-250 badge alone.

What Size Fuel Tank Does a 2026 F250 Have?

The 2026 F-250 gasoline pickup has a 34- or 48-gallon tank. Diesel configurations have 29-, 34-, or 48-gallon tanks, determined by wheelbase. The longest Crew Cab pickup uses 48 gallons with either fuel type.

Does an F250 Diesel Have a Bigger Tank Than a Gas Model?

Not necessarily. In 2026, a diesel Regular Cab has a 29-gallon tank while the comparable gas model has 34 gallons. Both fuels have a 48-gallon capacity in the long-wheelbase Crew Cab.

How Many Gallons Does an F250 Long Bed Hold?

There is no single long-bed answer. A 2004 long-box pickup is listed at 38 gallons, a 2016 diesel Regular Cab long-bed can have 26 gallons, and a 2026 long-wheelbase Crew Cab has 48 gallons. Match the complete configuration.

Can I Check My F250 Fuel Tank Size by VIN?

A Ford dealer may use your VIN to retrieve original build information, but VIN decoding by itself does not reliably prove the installed tank capacity. If the truck has been modified, confirm the tank and its part number independently.
