2013 Ford F150 Fuel Capacity – Tank Sizes, Range, And Identification
The 2013 Ford F-150 typically features one of two fuel tank sizes: a standard 26-gallon tank or an optional 36-gallon extended-range tank. Identifying your specific capacity is essential for calculating your maximum towing range and ensuring you never leave yourself stranded on a long-distance haul or off-road trail.
Whether you are planning a cross-country trip or just trying to figure out why your fill-up cost more than expected, knowing your 2013 ford f150 fuel capacity is the first step. Many owners find themselves confused because Ford offered different configurations based on wheelbase, trim level, and engine choice. In this guide, we will break down exactly how much fuel your truck holds and how that affects your real-world driving.
If you have ever stared at the gas pump wondering if your gauge is lying to you, you are not alone. It is a common question among F-150 owners, especially those who bought their trucks second-hand. We will help you identify your equipment and provide pro tips on maintaining your fuel system for the long haul.
This article provides a deep dive into the mechanical and practical aspects of your truck’s fuel system. We will cover everything from identification techniques to the impact of fuel weight on your payload capacity. Let’s get under the hood—and under the chassis—to find the answers you need.
Understanding the 2013 ford f150 fuel capacity Variations
The 2013 model year was a high point for the twelfth-generation F-150, offering a wide array of configurations. Because the F-150 is designed to be everything from a basic work truck to a luxury cruiser, Ford provided two primary fuel tank options. The standard capacity for most 4×2 and 4×4 models was 26 gallons (approximately 98 liters).
However, many buyers opted for the Extended Range fuel tank. This massive 36-gallon (136-liter) tank was a game-changer for those who used their trucks for towing or long-distance travel. It significantly increased the distance between gas stations, which is a major benefit when pulling a heavy trailer that drops your fuel economy into the single digits.
It is important to note that the SVT Raptor, Ford’s off-road powerhouse, came standard with the 36-gallon tank. This was necessary because the 6.2L V8 engine found in the Raptor is notoriously thirsty, especially when navigating sand dunes or technical trails. For the standard F-150 trims like the XLT or Lariat, the 36-gallon tank was often part of a towing package or a standalone option.
The 26-Gallon Standard Tank
The 26-gallon tank is the most common size found on shorter wheelbase trucks and base trims. If you have a Regular Cab or a SuperCab with a shorter bed, there is a high probability you have this tank. It provides a decent balance between weight and range for daily commuting and light-duty tasks.
One benefit of the smaller tank is weight savings. Gasoline weighs roughly 6 pounds per gallon. A full 26-gallon tank adds about 156 pounds to your truck, whereas a full 36-gallon tank adds 216 pounds. While 60 pounds might not seem like much, every bit counts when you are trying to stay within your Gross Vehicle Weight Rating (GVWR).
The 36-Gallon Extended Range Tank
The 36-gallon tank is the “gold standard” for F-150 enthusiasts. It is almost always found on the SuperCrew models with the 6.5-foot or 5.5-foot beds. If you find yourself putting more than 30 gallons into your truck at a gas station when the “Low Fuel” light comes on, you definitely have the extended-range version.
This tank is physically longer and takes up more space along the frame rail. For off-roaders, this extra size is a double-edged sword. While you get more range, the tank is a larger target for rocks and debris. If you plan on hitting the trails, ensure your 36-gallon tank is protected by a heavy-duty skid plate.
How to Verify Your 2013 Ford F-150 Fuel Capacity
If you are unsure which tank is installed on your vehicle, there are several reliable ways to check. You do not need to be a master mechanic to find this information. The most accurate method is to check your original window sticker or use a VIN decoder online, which can list the specific options installed at the factory.
Another practical way to check is to look at your instrument cluster. When your fuel light comes on, the “Distance to Empty” (DTE) calculation can give you a hint. If the truck says you have 50 miles left and you fill up 22 gallons, you likely have a 26-gallon tank. If you fill up 31 gallons, you have the 36-gallon tank.
You can also perform a visual inspection under the truck. The 36-gallon tank is quite long, stretching significantly further toward the rear axle than the 26-gallon version. If the tank appears to take up most of the space between the transfer case and the rear differential, it is the 36-gallon unit. Look for a part number sticker on the bottom of the tank if it is still legible.
Using the Ford ETIS or VIN Decoders
Ford’s official systems or reputable third-party VIN decoders are excellent resources. By entering your 17-digit Vehicle Identification Number, you can see the build sheet. Look for terms like “Standard Fuel Tank” or “Extended Range Fuel Tank” in the equipment list.
This is especially helpful if you are buying a used truck. Knowing the 2013 ford f150 fuel capacity beforehand can help you decide if the truck fits your needs for overlanding or heavy towing. Many owners consider the 36-gallon tank a “must-have” feature for resale value.
The “Empty” Reserve Mystery
It is a common observation that F-150 fuel gauges are conservative. When the gauge reads “Empty,” there is usually a reserve of 2 to 4 gallons left in the tank. This is a safety feature designed by Ford engineers to prevent you from running the fuel pump dry.
Running a fuel tank completely empty is dangerous for the fuel pump. The gasoline actually acts as a coolant and lubricant for the pump motor. If you consistently run the tank until it is bone dry, you risk an expensive repair. Always aim to refill when you hit the quarter-tank mark.
Impact of Engine Choice on Range and Capacity
The 2013 F-150 featured four distinct engines, each with its own fuel consumption characteristics. While the tank size remains constant (either 26 or 36 gallons), your effective range will vary wildly depending on what is under the hood. The engine’s efficiency determines how far those gallons will actually take you.
For example, the 3.7L Ti-VCT V6 was the base engine, offering the best unladen fuel economy. When paired with the 26-gallon tank, it provides a respectable highway range. However, if you have the 6.2L V8, your range will be significantly shorter due to its higher fuel consumption, making the 36-gallon tank almost a necessity.
- 3.7L V6: Best for light duty; decent range even with the 26-gallon tank.
- 5.0L V8: The “Coyote” engine; offers a balance of power and efficiency, thrives with the 36-gallon tank.
- 3.5L EcoBoost: Twin-turbocharged power; can be efficient but “drinks” fuel when under heavy boost or towing.
- 6.2L V8: Found in the Raptor and Lariat Limited; high fuel consumption requires the extended tank for any serious travel.
The 3.5L EcoBoost is a particularly interesting case. While it is marketed for efficiency, many owners find that “when you use the boost, you lose the eco.” If you are towing a 7,000-pound trailer with an EcoBoost, your 2013 ford f150 fuel capacity will feel much smaller than it actually is because your MPG might drop to 9 or 10.
Maintenance Tips for Your F-150 Fuel System
To keep your fuel system running efficiently, regular maintenance is required. The 2013 F-150 uses a “lifetime” fuel filter that is integrated into the fuel pump assembly inside the tank. This means you do not have a traditional external filter to change every 30,000 miles.
However, because the filter is not easily serviceable, you must be careful about the quality of fuel you use. Avoid filling up at stations while a tanker truck is refilling the underground tanks, as this can stir up sediment. Sediment and debris are the primary enemies of an in-tank fuel pump and filter assembly.
Another common issue with the 2013 model is the EVAP Purge Valve. If you notice your truck struggling to start after a fill-up, or if you get a check engine light with a code like P0456, the purge valve might be stuck. This part is relatively inexpensive and a common DIY fix for most owners.
Protecting the Fuel Pump
As mentioned earlier, the fuel pump is submerged in gasoline to stay cool. In hotter climates, such as the Southwest, this is even more critical. If you frequently drive with less than a quarter tank, the pump can overheat, leading to premature failure and a bill that can easily exceed $700.
If you are an off-roader, be mindful of fuel slosh. When navigating steep inclines or declines with a low fuel level, the fuel can move away from the pump pickup. This can cause the engine to stumble or stall at the worst possible moment. Always head into the trails with a full tank.
The Importance of the Capless Fuel System
The 2013 F-150 features the “Easy Fuel” capless filler neck. While convenient, it requires care. Ensure that the spring-loaded doors are free of dirt and debris. If dirt gets trapped in the seals, it can trigger a “Check Fuel Fill Inlet” message on your dashboard.
If you ever need to add fuel from a portable gas can, you must use the specific funnel provided with the truck. This funnel is usually located under the rear seat or with the jack tools. It is specially sized to open both doors of the capless system without damaging the sensitive seals.
Upgrading Your Fuel Capacity for Long-Distance Travel
For some owners, even the 36-gallon 2013 ford f150 fuel capacity is not enough. This is especially true for overlanders who travel into remote areas or those who tow large fifth-wheel trailers. If you find yourself carrying multiple 5-gallon Jerry cans, it might be time to look at an upgrade.
One popular option is an auxiliary fuel tank. These are typically mounted in the truck bed and can add 30 to 50 gallons of extra capacity. Some systems are “transfer tanks” where you manually pump fuel into the main tank, while others are “in-line” systems that automatically keep the main tank full.
While most large-capacity replacement tanks (like those from Titan or S&B) are designed for diesel trucks, there are specialized options for gasoline engines. However, these are often more complex due to the EVAP system requirements for gasoline. Always consult with a professional before modifying your fuel system to ensure it remains emissions-compliant and safe.
Weight and Balance Considerations
When you increase your fuel capacity, you must consider the weight. A 50-gallon auxiliary tank plus the standard 36-gallon tank equals 86 gallons of fuel. At roughly 6 pounds per gallon, that is 516 pounds of fuel alone. This significantly reduces your remaining payload capacity.
If you are already close to your truck’s weight limit with a trailer or camping gear, adding a massive amount of fuel could put you over the legal limit. This affects braking distances and handling. Always weigh your truck at a CAT scale if you are unsure of your total load.
Frequently Asked Questions About 2013 ford f150 fuel capacity
Can I swap my 26-gallon tank for a 36-gallon tank?
Yes, it is a common swap among F-150 owners. You will need the 36-gallon tank, the corresponding heat shields, and the longer fuel pump assembly. Additionally, you must use a tool like FORScan to update the truck’s computer so the “Distance to Empty” reads correctly.
How many miles can a 2013 F-150 go on a full tank?
This depends on the engine and tank size. A 3.5L EcoBoost with a 36-gallon tank getting 18 MPG has a theoretical range of 648 miles. A 6.2L V8 with a 26-gallon tank getting 12 MPG only has a range of 312 miles. Towing will usually cut these numbers in half.
Why does my 36-gallon tank only take 30 gallons to fill?
Ford designs the fuel gauge to show “Empty” when there are still about 4 to 6 gallons left in the tank. This is to protect the fuel pump from overheating and to ensure you have a “limp-home” reserve. It is perfectly normal behavior for the 2013 model year.
Is the fuel tank on the 2013 F-150 plastic or metal?
The fuel tanks on these trucks are made of a high-density polyethylene (HDPE) plastic. This material is excellent because it does not rust or corrode like old steel tanks. However, it can be punctured by sharp rocks, which is why skid plates are vital for off-roading.
Does the fuel capacity change for the FX4 or STX trims?
Trim levels like FX4 or STX do not dictate the tank size directly; rather, the wheelbase and optional packages do. However, the FX4 often came with the 36-gallon tank as standard or as part of its off-road oriented equipment list. Always verify by the VIN.
Final Thoughts on Managing Your F-150’s Fuel
Understanding your 2013 ford f150 fuel capacity is more than just a trivia point; it is a vital part of being a responsible truck owner. Whether you have the standard 26-gallon tank or the long-range 36-gallon version, knowing your limits allows you to plan your trips with confidence and avoid unnecessary stress.
Remember that your truck’s range is a dynamic number. It changes with the wind, the weight of your cargo, and the health of your engine. By keeping your fuel system maintained and respecting the “quarter-tank rule,” you can ensure your F-150 remains a reliable partner for many miles to come.
If you are considering an upgrade or a tank swap, take the time to do it right. Use the proper tools, update your software, and always prioritize safety when working around gasoline. Your F-150 is a versatile machine, and having the right fuel capacity only makes it better. Stay safe and stay comfortable on the road!
