2013 Ford F150 Gas Tank Size – Determine Your Capacity For Better
The 2013 Ford F-150 offers two primary fuel capacities: a standard 26-gallon tank and an optional 36-gallon extended-range tank. Knowing your specific configuration is essential for calculating towing range, planning off-road excursions, and accurately diagnosing fuel gauge issues.
We have all been there, driving down a desolate stretch of highway while the low-fuel light glows ominously on the dashboard. You start doing the mental math, wondering if you have enough fuel to reach the next station or if you are about to become a pedestrian.
For owners of this specific model year, confirming your 2013 ford f150 gas tank size is the first step toward stress-free travel and smarter maintenance. Whether you are hauling a trailer or hitting the trails, knowing your volume changes everything.
In this guide, I will walk you through the different tank options available for the 2013 lineup, how to verify which one is bolted to your frame, and how to maximize your range. Let’s dive into the details so you can drive with confidence.
Understanding the 2013 ford f150 gas tank size Options
Ford designed the 2013 F-150 to be incredibly versatile, which meant offering different fuel capacities to suit different needs. Most buyers had to choose between the standard setup and the heavy-duty option during the initial purchase.
The standard 26-gallon tank is the most common find on the used market, especially for trucks configured with a regular cab or a shorter wheelbase. This size provides a decent balance between weight savings and driving range for daily commuting.
However, many owners opted for the 36-gallon extended-range fuel tank. This larger reservoir was frequently paired with the 4×4 drivetrain, the EcoBoost engine, or higher trim levels like the Lariat, King Ranch, and Platinum.
The Regular Cab and SuperCab Variations
If you own a regular cab with a 6.5-foot bed, you are almost certainly looking at a 26-gallon capacity. The physical space beneath the truck limits how large the tank can be without interfering with other components.
SuperCab models with the 145-inch wheelbase also typically default to the 26-gallon tank unless the original owner specifically checked the box for the extended-range upgrade. Always check the window sticker if you still have it.
The SuperCrew and Long Bed Advantage
The SuperCrew configuration, which features four full-sized doors, often came equipped with the 36-gallon tank as part of a towing package. The longer frame provides the necessary real estate to house the larger plastic fuel cell.
For those with the 8-foot long bed, the 36-gallon tank was much more common. These trucks are built for work and long-distance hauling, making the increased capacity a vital feature for professional users.
How to Verify Your 2013 ford f150 gas tank size
If you bought your truck used, you might not know which tank you have. Relying on the fuel gauge alone can be misleading because the “distance to empty” calculation is based on recent driving habits and reserve fuel levels.
One of the easiest ways to check is by looking at your driver-side door jamb. The Safety Compliance Certification Label contains various codes, including the wheelbase, which can give you a hint about the likely tank size.
A more definitive method is to use a VIN decoder. By entering your Vehicle Identification Number into an online Ford database, you can pull up the original build sheet to see exactly what equipment was installed at the factory.
The “Gas Station Test”
You can also get a rough idea the next time you fill up from a nearly empty state. If your low-fuel light comes on and you can only pump 21 or 22 gallons before the nozzle clicks off, you have a 26-gallon tank.
If you find yourself pumping 30 or 32 gallons after the warning light appears, you definitely have the 36-gallon version. Keep in mind that Ford builds in a generous reserve, so you will rarely pump the full rated capacity.
Physical Inspection Under the Truck
If you are comfortable sliding under the vehicle, you can visually inspect the tank. The 36-gallon tank is significantly longer and occupies more space along the inner frame rail than the standard version.
Look for a part number sticker on the side or top of the tank. While these are often covered in road grime, a quick wipe with a rag might reveal a code that you can cross-reference with a Ford parts catalog.
Impact of Tank Size on Towing and Off-Roading
Knowing the 2013 ford f150 gas tank size allows you to plan for the “worst-case scenario” fuel economy. When towing a heavy travel trailer, your MPG can drop into the single digits, making every gallon count.
With a 26-gallon tank and a towing average of 9 MPG, your total range is only about 234 miles. However, with the 36-gallon tank, that range jumps to 324 miles, giving you much more breathing room between stops.
For off-roaders, the larger tank is a massive benefit. If you are crawling through trails in 4-Low, your engine is working hard while the truck moves slowly, which consumes fuel at a much higher rate per mile.
Planning for Remote Areas
If you plan to visit remote locations like Death Valley or the North Maine Woods, the 36-gallon tank is almost a requirement. It reduces the need to carry multiple heavy jerry cans on your bed rack or bumper.
Always remember the “Rule of Thirds” when adventuring: use one-third of your fuel to get in, one-third to get out, and keep one-third as a safety reserve for emergencies or getting lost.
Weight Considerations
It is worth noting that fuel is heavy, weighing roughly 6 pounds per gallon. A full 36-gallon tank adds about 216 pounds to your vehicle, whereas a 26-gallon tank adds only 156 pounds.
While this 60-pound difference is negligible for a half-ton truck, every bit of weight affects your payload capacity. If you are already at your limit with passengers and gear, keep this in mind.
Common Fuel System Maintenance for the 2013 F-150
Regardless of your tank size, the fuel system requires periodic attention to stay reliable. The 2013 model year uses a returnless fuel system, which simplifies plumbing but places more stress on the pump.
One common issue for F-150s of this era is the Fuel Pump Driver Module (FPDM). This small electronic component is located on a crossmember above the spare tire and is prone to corrosion and cracking.
If the FPDM fails, your truck will crank but won’t start, or it may die unexpectedly while driving. I recommend inspecting this module annually and replacing it if you see any signs of oxidized aluminum or housing damage.
The Importance of Top-Tier Fuel
Modern engines, especially the 3.5L EcoBoost found in many 2013 models, are sensitive to fuel quality. Using “Top Tier” gasoline helps prevent carbon buildup on the intake valves and fuel injectors.
Because the EcoBoost is direct-injected, it doesn’t have fuel washing over the back of the valves to keep them clean. High-quality additives in the fuel are your first line of defense against performance degradation.
Replacing the Fuel Filter
On the 2013 Ford F-150, the fuel filter is technically “lifetime” and is integrated into the fuel pump assembly inside the tank. There is no external filter to change during a routine tune-up.
If you suspect a clog, you will likely need to replace the entire fuel pump. To avoid this expensive repair, never let your fuel level get extremely low, as the pump relies on the surrounding gasoline for cooling.
Upgrading Your Fuel Tank: Is It Possible?
If you discovered that you have the 26-gallon tank and wish you had the 36-gallon version, you are in luck. Many DIYers have successfully performed a tank swap using salvaged parts or OEM kits.
However, this is not a simple “plug and play” job. You will need the larger tank, the corresponding fuel sending unit, and potentially new mounting straps. The frame holes are usually pre-drilled for both sizes.
The most technical part of the swap is updating the truck’s computer. You must use software like FORScan to tell the instrument cluster that it now has a 36-gallon capacity so the “Distance to Empty” remains accurate.
Safety Precautions for Tank Removal
Working with fuel is inherently dangerous. If you decide to swap or replace your tank, ensure you are working in a well-ventilated area far away from any pilot lights or sparks.
Always use a dedicated fuel transfer pump to empty the tank as much as possible before dropping it. A full tank is nearly impossible to balance on a floor jack and can lead to serious injury if it falls.
Wear nitrile gloves and eye protection. Gasoline is a harsh solvent that can irritate your skin and cause permanent eye damage if splashed during a line disconnection.
Frequently Asked Questions About 2013 ford f150 gas tank size
What is the most common 2013 ford f150 gas tank size?
The 26-gallon tank is the standard offering for most trim levels and cab configurations. The 36-gallon tank was a popular optional upgrade, particularly on 4×4 and EcoBoost-equipped trucks.
Can I put a 36-gallon tank in a truck that came with a 26-gallon tank?
Yes, it is a common modification. You will need the tank, the correct fuel pump assembly for the larger tank, and you must recalibrate the truck’s software to recognize the new capacity.
Why does my fuel gauge say empty when I still have 5 gallons left?
Ford designs their fuel systems with a “reserve” capacity. This prevents the fuel pump from running dry (which can cause it to overheat) and gives the driver a safety margin to find a station.
Does the Raptor have a different gas tank size?
The 2013 Ford Raptor came standard with the 36-gallon tank. Given its high-performance 6.2L V8 engine and off-road focus, the extra capacity was necessary to provide a reasonable driving range.
How much does it cost to replace a fuel tank?
If you are buying a new OEM tank, expect to pay between $600 and $900 for the part alone. Labor at a professional shop can add another $300 to $500 depending on your local rates.
Maximizing Your F-150’s Range and Efficiency
Regardless of your 2013 ford f150 gas tank size, how you drive has the biggest impact on your range. Small changes in habits can lead to significant savings at the pump over time.
Keep your tires properly inflated to the pressure listed on your door placard. Low tire pressure increases rolling resistance, which forces your engine to work harder and burn more fuel.
On the highway, try to maintain a steady speed. Using cruise control can help prevent the “accordion effect” of constant acceleration and braking, which is a major fuel killer for heavy trucks.
Finally, keep your bed clear of unnecessary weight. Carrying around 200 pounds of old car parts or landscape rocks in the back is like driving with an extra passenger you don’t need, reducing your MPG every mile.
By understanding your fuel capacity and maintaining your system, you ensure that your Ford F-150 remains the reliable workhorse it was built to be. Stay safe on the road and enjoy the journey!
