Understanding Your 2017 ford f150 fuel capacity Options
Ford designed the 2017 F-150 with versatility in mind, which means there is no “one size fits all” fuel tank. The standard tank for most configurations is the 23-gallon unit, which provides a balance between weight savings and decent driving range. This tank is commonly found on shorter wheelbase models and standard work trucks.
For those with specific cab and bed combinations, Ford also offered a 26-gallon tank. This was often the default for Regular Cab and SuperCab models with the 122-inch wheelbase configuration. While the 3-gallon difference might seem small, it can offer an extra 40 to 60 miles of highway driving depending on your engine.
The most sought-after option for enthusiasts and long-haulers is the 36-gallon extended-range fuel tank. This massive tank was an optional upgrade for most trims and came standard on the Raptor. Having a 36-gallon 2017 ford f150 fuel capacity allows for incredible range, often exceeding 700 miles on the highway when paired with the efficient 2.7L EcoBoost engine.
Configuration Breakdown by Wheelbase
The physical space available under the chassis determines which tank Ford could install at the factory. Short-bed SuperCrews often have different clearance requirements than long-bed Regular Cabs. Understanding these physical constraints helps you narrow down which tank you likely have.
Generally, the 36-gallon tank requires a longer frame or specific mounting brackets that were not available on every single sub-model. If you bought your truck used, it is possible the original owner opted for the extended range package, which was a very popular add-on for the 2017 model year.
If you are planning an off-road build, knowing your tank size is critical for weight distribution. A full 36-gallon tank adds roughly 216 pounds of weight to the driver’s side of the vehicle. This is a significant factor when tuning your suspension or calculating payload capacity for a truck camper.
How to Identify Your Specific Tank Size
If you are the second or third owner, you might not know which 2017 ford f150 fuel capacity you are working with. The easiest way to check is to look at your original window sticker if you have it. Look for the “Optional Equipment” section to see if the “36 Gallon Extended Range Fuel Tank” is listed.
Another reliable method is to use a VIN decoder or visit a Ford dealership parts counter with your Vehicle Identification Number. The VIN contains the specific build data for your truck, including the fuel system configuration. This is much more accurate than guessing based on how much gas you pump at the station.
You can also perform a “low fuel” test, though this is less scientific. When your Distance to Empty (DTE) hits zero, the truck usually has a 2-3 gallon “reserve” left. If you fill up at that point and the pump clicks off at 20 gallons, you almost certainly have the 23-gallon tank.
Physical Inspection Under the Truck
For those who prefer a hands-on approach, you can slide under the truck with a flashlight. The fuel tank is located on the driver’s side, inside the frame rail. The 36-gallon tank is notably long, stretching from the rear axle almost to the transmission crossmember.
Look for a part number sticker on the side or top of the plastic tank housing. Engineering codes like FL34-9002 can often be cross-referenced online to confirm the exact volume. Be careful not to mistake the charcoal canister or heat shields for the tank itself.
If you see a large gap between the front of the tank and the transmission, you likely have the smaller 23-gallon version. The 36-gallon tank fills nearly all the available longitudinal space under the cab and bed. This visual check is a quick way for DIYers to verify their 2017 ford f150 fuel capacity.
The Impact of Engine Choice on Driving Range
While the 2017 ford f150 fuel capacity tells you how much gas you can carry, your engine determines how fast you burn it. In 2017, Ford offered several engines, including the 3.5L Ti-VCT V6, the 2.7L EcoBoost, the 5.0L V8, and the high-output 3.5L EcoBoost. Each has a different appetite for fuel.
The 2.7L EcoBoost is the efficiency king for this model year. When paired with the 36-gallon tank, it creates a “long-legged” highway cruiser. Owners often report being able to drive from Los Angeles to Salt Lake City on a single fill-up, which is a testament to Ford’s aerodynamics and engine tuning.
Conversely, the 5.0L V8 and the 3.5L EcoBoost (especially when towing) will drain that capacity much faster. If you have the 23-gallon tank and the V8, your stops at the pump will be frequent. This is why many owners who tow trailers eventually look into swapping for a larger factory tank.
Towing and Payload Considerations
When you are towing a heavy trailer, your fuel economy can drop into the single digits. On a 23-gallon tank, an average of 9 MPG gives you a theoretical range of only 207 miles. However, you should never run a tank to bone dry, meaning your effective range is closer to 170 miles.
With the 36-gallon 2017 ford f150 fuel capacity, that same 9 MPG gives you a much more manageable 324-mile range. This allows you to bypass expensive gas stations near highway interchanges and find better prices. It also provides a safety buffer if you encounter unexpected head winds or detours.
Always remember that fuel has weight. If you are maxing out your payload with gear and passengers, carrying 36 gallons of fuel uses up about 220 pounds of your available capacity. For a half-ton truck, this is a factor you must calculate before heading out on a cross-country trip.
Common Problems with the 2017 F-150 Fuel System
Even with the right 2017 ford f150 fuel capacity, hardware failures can lead to range issues or poor performance. One common complaint among owners is an inaccurate fuel gauge. This is often caused by a failing fuel level sender located inside the tank on the fuel pump assembly.
Another issue involves the EVAP system, specifically the vapor canister. If you have a habit of “topping off” the tank after the pump clicks, liquid fuel can enter the charcoal canister. This leads to check engine lights and difficulty starting the truck after refueling.
If you notice a whistling sound or a strong smell of gasoline near the rear of the truck, inspect the fuel filler neck. The 2017 F-150 uses a “Capless Fuel Fill” system. While convenient, dirt and debris can sometimes prevent the internal flap from sealing correctly, leading to evaporative leaks.
Fuel Pump Health and Maintenance
The fuel pump in your F-150 is cooled by the gasoline surrounding it. If you constantly run your tank down to the “Low Fuel” warning, the pump can overheat. This is especially risky in hot climates or during high-demand situations like off-roading in deep sand.
To prolong the life of your fuel pump, try to keep the tank at least a quarter full. This ensures the pump remains submerged and cool. If you hear a high-pitched whining noise from the tank area, it may be a sign that your pump is beginning to fail and needs professional attention.
While the 2017 F-150 does not have a traditional “serviceable” fuel filter (it uses a lifetime screen on the pump), using high-quality Top Tier gasoline is vital. This helps keep the fuel injectors clean and ensures the engine maintains its factory-rated efficiency over the long term.
Upgrading Your Fuel Capacity for Off-Roading
For serious overlanders and off-roaders, even the 36-gallon 2017 ford f150 fuel capacity might not be enough. If you are exploring remote areas like the Mojave Road or the backwoods of Montana, carrying extra fuel is a necessity. You have a few options for increasing your range.
The most common DIY upgrade is carrying RotopaX or traditional Jerry cans. These can be mounted to a bed rack or a swing-away bumper. Always ensure external fuel containers are securely fastened and mounted away from exhaust heat sources to prevent fire hazards.
For a more permanent solution, companies like Transfer Flow offer midship replacement tanks. These high-capacity steel or heavy-duty plastic tanks can replace your factory 23-gallon tank with something much larger. Note that these upgrades often require reprogramming the truck’s computer so the DTE display remains accurate.
Transfer Tanks and Auxiliary Systems
If you use your truck for work or long-distance hauling, a bed-mounted transfer tank might be the answer. These tanks sit in the front of the truck bed and can hold an additional 30 to 50 gallons of fuel. Some systems are designed to “gravity feed” into the main tank, while others use an electric pump.
Be aware that adding a transfer tank significantly impacts your bed space and payload. A 50-gallon transfer tank plus the fuel inside can weigh over 400 pounds. Ensure your rear leaf springs and tires are rated for the additional constant load before installing such a system.
When installing any auxiliary fuel system, always prioritize safety. Use braided fuel lines and high-quality fittings. If you are not comfortable working with high-pressure fuel systems, it is best to have a certified technician perform the installation to avoid leaks or fire risks.
Expert Tips for Maximizing Every Gallon
Regardless of your 2017 ford f150 fuel capacity, how you drive has the biggest impact on your range. The 10-speed automatic transmission in the 2017 model is designed to keep the engine in its most efficient power band. Use “Eco Mode” if your truck is equipped with it to soften throttle response.
Maintain proper tire pressure. Under-inflated tires increase rolling resistance, which can sap your fuel economy by as much as 3%. This is especially important for off-roaders who “air down” for trails; remember to air back up as soon as you hit the pavement.
Keep an eye on your air filter. A clogged filter restricts airflow, forcing the engine to work harder and burn more fuel. Replacing a dirty filter is one of the cheapest and easiest DIY tasks that can actually save you money at the pump over time.
Aerodynamics and Bed Covers
At highway speeds, wind resistance is your biggest enemy. Adding a tonneau cover or a bed cap can improve airflow over the rear of the truck, potentially increasing your MPG. Avoid leaving the tailgate down, as modern trucks are actually more aerodynamic with the tailgate closed.
If you have a lift kit or large, knobby mud-terrain tires, your fuel efficiency will naturally drop. The increased frontal area and rolling resistance mean you will never hit the EPA-estimated mileage. Factor this into your trip planning so you don’t get caught short between stations.
Lastly, use cruise control on flat highways. It prevents the subtle “surging” of the accelerator pedal that occurs with manual foot control. Consistent speed is the key to getting the most out of your 2017 ford f150 fuel capacity and reaching your destination safely.
Frequently Asked Questions About 2017 ford f150 fuel capacity
How many miles can I drive when the “Low Fuel” light comes on?
In most 2017 F-150s, the light triggers when you have approximately 1/16th of a tank or about 35-50 miles of range left. However, this varies based on your current MPG. It is never recommended to drive until the light comes on, as it can damage the fuel pump.
Can I swap my 23-gallon tank for a factory 36-gallon tank?
Yes, this is a popular modification. You will need the 36-gallon tank, the matching fuel pump assembly, and new heat shields. You will also need to use a tool like FORScan to update the truck’s PCM so the fuel gauge reads correctly.
Does the 2017 Ford Raptor have a different fuel capacity?
The 2017 Raptor came standard with the 36-gallon 2017 ford f150 fuel capacity for the SuperCrew model. The SuperCab Raptor featured a 26-gallon tank due to the shorter wheelbase and frame constraints. Always verify your cab style when looking up Raptor specs.
What type of gas should I put in my 2017 F-150?
Ford recommends 87 octane regular unleaded for all 2017 engines. However, for best performance while towing or in hot weather, 91 octane or higher is recommended, especially for the EcoBoost engines to prevent spark knock and maintain power.
Why does my “Distance to Empty” change so much?
The DTE calculation is based on your average fuel economy over the last 500 miles. If you just finished a long towing trip and then start driving unladen on the highway, the computer will slowly adjust the estimate upward as your MPG improves.
Conclusion: Mastering Your Truck’s Range
Understanding the 2017 ford f150 fuel capacity is more than just a technical detail; it is a vital part of vehicle ownership. Whether you have the standard 23-gallon tank or the long-range 36-gallon version, knowing your limits allows you to push your truck to its full potential while staying safe.
From identifying your tank size via the VIN to maintaining the health of your fuel pump, every bit of knowledge helps you avoid costly repairs and inconvenient breakdowns. Remember to treat your fuel system with care by using quality fuel and avoiding the “empty” mark on your gauge.
