2017 Ford F 150 Gas Tank Size – Find Your Fuel Capacity And Range
The 2017 Ford F-150 features three primary fuel tank capacities: 23 gallons, 26 gallons, and a 36-gallon extended-range version. Your specific capacity depends on the cab style, wheelbase, and whether the original owner selected the optional larger tank during the initial build.
Have you ever been cruising down a desolate stretch of highway, watching the needle dip toward “E,” and wondered exactly how much “cushion” you really have? Understanding your 2017 ford f 150 gas tank size is the first step toward mastering your truck’s long-distance capabilities.
Whether you are planning a cross-country towing trip or prepping for a weekend of off-road trail riding, fuel management is a critical skill. This guide will help you identify your specific tank capacity and explain how it impacts your daily driving and utility.
In the sections below, we will dive into the technical specifications of the 2017 model year, explore how to verify your equipment, and discuss why the extended-range tank is such a sought-after feature. Let’s get your questions answered so you can get back on the road.
Understanding Your 2017 ford f 150 gas tank size Options
The 2017 model year was a pivotal time for the F-150, as Ford continued to refine the aluminum-body platform. Because these trucks are highly customizable, Ford offered three different fuel reservoirs to match the varied needs of fleet buyers and recreational users.
The 23-gallon tank is the standard offering for the majority of F-150 configurations. It provides a balance between weight savings and a respectable driving range for daily commuting and light-duty work.
A 26-gallon tank exists specifically for certain Regular Cab and SuperCab models with the 122-inch wheelbase. This minor increase in volume is often overlooked but provides a slight edge for those with shorter truck frames.
Finally, the 36-gallon extended-range fuel tank is the gold standard for many enthusiasts. This tank is often bundled with the Max Trailer Tow Package, allowing for massive distances between fill-ups, which is essential when your MPG drops while hauling a heavy trailer.
The 23-Gallon Standard Tank
If you have a standard SuperCrew or SuperCab without any special towing packages, you likely have the 23-gallon unit. This tank is designed to keep the truck’s curb weight lower, which helps slightly with the payload capacity listed on your door jamb.
While 23 gallons might seem small for a full-size pickup, the 2017 engines—particularly the 2.7L EcoBoost—are remarkably efficient. This combination still allows for a highway range of over 500 miles under ideal conditions.
The 36-Gallon Extended-Range Tank
The 36-gallon tank is a favorite among the off-road and overlanding community. Having nearly 40 gallons of fuel on board means you can explore remote trails without the immediate need for external jerry cans or auxiliary fuel cells.
When you are trying to determine your 2017 ford f 150 gas tank size, keep in mind that the 36-gallon version is a physical monster. It takes up significantly more space under the frame and adds about 216 pounds to the truck’s weight when completely full.
How to Identify Which Fuel Tank is in Your F-150
Identifying your fuel capacity isn’t always as simple as looking at the trim level. Since the larger tank was a standalone option for many years, a base XL trim could potentially have the 36-gallon tank while a loaded Platinum might only have the 23-gallon version.
The most accurate way to verify your capacity is by checking the original window sticker. If you don’t have the physical paper, you can often find digital versions online using your Vehicle Identification Number (VIN) through various Ford enthusiast portals.
Finding the exact 2017 ford f 150 gas tank size is easier if you look at the window sticker. Look for the “Optional Equipment” section; if it lists “36 Gallon Extended Range Fuel Tank,” you have the large one. If it isn’t listed, you likely have the standard 23 or 26-gallon unit.
The “Fill-Up” Method
If you want a low-tech way to check, wait until your “Distance to Empty” (DTE) reads about 20 miles. Head to the gas station and fill the tank until the pump clicks off once; if you pump in 30 or more gallons, you definitely have the extended-range tank.
Be careful with this method, as modern fuel pumps are cooled by the gasoline they are submerged in. Running your tank extremely low consistently can lead to premature pump failure, so only do this once for verification purposes.
Checking the Instrument Cluster
You can also look at your truck’s digital display settings. In the “Towing” or “Trip/Fuel” menus, the DTE calculation logic is programmed based on the tank size. If your DTE shows 600+ miles after a full fill-up, you are almost certainly rocking the 36-gallon reservoir.
The Impact of Tank Size on Towing and Payload
For the DIY mechanic or the weekend warrior, understanding the relationship between fuel and weight is vital. Gasoline weighs approximately 6 pounds per gallon, meaning a full 36-gallon tank adds roughly 78 pounds more than the 23-gallon tank.
This weight counts against your total payload capacity. If you are already pushing the limits of your truck’s hauling ability with a heavy tongue weight and a bed full of gear, that extra fuel weight is a factor you must calculate.
However, for those who tow frequently, the 36-gallon tank is a lifesaver. Towing a large travel trailer can drop your fuel economy to 8-10 MPG. With a 23-gallon tank, you would be stopping every 180 miles, whereas the larger tank pushes that interval to over 300 miles.
Optimizing Your Payload
If you have the smaller tank and need more range, you might be tempted to carry extra fuel in the bed. Always use DOT-approved containers and secure them tightly to prevent shifting or spills during aggressive maneuvers or off-road driving.
For those with the large tank, remember that you don’t always have to fill it to the brim. If you are doing heavy hauling where every pound of payload matters, carrying only half a tank can “buy” you an extra 100 pounds of capacity for your gear.
Range and Fuel Efficiency: Doing the Math
The 2017 F-150 came with several engine options: the 3.5L Ti-VCT V6, the 2.7L EcoBoost, the 5.0L V8, and the 3.5L EcoBoost. Each of these engines interacts differently with your 2017 ford f 150 gas tank size to determine your total range.
The 2.7L EcoBoost is generally the fuel-sipping champion of the group. Paired with a 36-gallon tank, it is theoretically possible to achieve a highway range of nearly 800 miles on a single fill-up, assuming a light foot and no cargo.
The 5.0L V8 and the 3.5L EcoBoost are more thirsty, especially under load. Owners often ask if the 2017 ford f 150 gas tank size can be upgraded after purchase. While possible, it is a significant undertaking involving new straps, heat shields, and a recalibration of the truck’s computer.
Calculating Your Real-World Range
To find your specific range, multiply your average MPG by your tank size. For example, if you average 17 MPG and have the 23-gallon tank, your total range is 391 miles. Always subtract 50 miles from that total to account for a safety reserve.
Off-roaders should be even more conservative. Low-range 4WD driving and crawling through sand or mud can cut your fuel economy in half. Always plan your trail exits based on having at least a quarter-tank of fuel remaining.
Upgrading or Replacing Your F-150 Fuel Tank
If you find that your current tank is too small for your adventures, you aren’t stuck forever. Many owners choose to swap their standard tank for the 36-gallon OEM version or even larger aftermarket tanks from companies like Transfer Flow or S&B Tanks.
Swapping a fuel tank is a job a dedicated DIYer can handle, but it requires caution. You will need a transmission jack or a second set of hands to lower the tank safely, especially if there is any residual fuel left inside.
You will also need to update the truck’s software. Using a tool like FORScan and an OBDII adapter, you can change the tank size value in the Body Control Module (BCM). This ensures your DTE and fuel gauge remain accurate after the swap.
Safety Steps for Fuel System Work
- Work in a well-ventilated area, preferably outdoors, to avoid vapor buildup.
- Disconnect the negative battery terminal to eliminate any risk of electrical sparks.
- Use a siphon pump to drain as much fuel as possible before loosening the mounting straps.
- Always replace the fuel pump O-ring and check the condition of the filler neck hose during the process.
Common Issues and Maintenance for 2017 F-150 Fuel Systems
The fuel system on the 2017 F-150 is generally robust, but there are a few things to keep an eye on. One common complaint is the “slow fill” issue, where the gas pump constantly clicks off even when the tank is empty.
This is usually caused by a clogged EVAP canister or a pinched vent line. If you frequently drive on dusty gravel roads or go off-roading, dirt can enter the vent system and restrict the airflow needed during refueling.
Another point of maintenance is the fuel pump driver module. While more common on older Fords, the 2017 models can still experience corrosion or electrical issues at the connector. Inspecting this area during your oil changes can prevent a “crank but no start” scenario.
Protecting Your Tank Off-Road
If you take your F-150 into rocky terrain, the fuel tank is a vulnerable target. It is made of high-density plastic, which is durable but can be punctured by sharp rocks. Installing an aftermarket skid plate is a smart investment for any trail rider.
Most FX4 packages come with a factory “skid plate,” but these are often thin and offer limited protection. For serious rock crawling, look for 3/16-inch aluminum or steel plates that bolt directly to the frame rails.
Frequently Asked Questions About 2017 Ford F-150 Gas Tank Size
Can I put a 36-gallon tank in a Regular Cab F-150?
Generally, no. The 36-gallon tank is physically too long for the short-wheelbase Regular Cab (122-inch WB). It is typically reserved for the 145-inch, 157-inch, and 163-inch wheelbase configurations found on SuperCabs and SuperCrews.
Does the 2017 F-150 Raptor have a different tank size?
The 2017 Raptor comes standard with a 26-gallon tank on the SuperCab models and the 36-gallon tank on the SuperCrew models. Because the Raptor is built for high-speed desert running, the larger tank is almost a necessity.
Why does my F-150 take less gas than the rated capacity?
Ford builds in a reserve capacity. When your gauge hits “0 miles to empty,” there are usually 2 to 3 gallons of fuel left in the tank. This prevents the fuel pump from running dry and gives you a final chance to find a station.
Is there a fuel filter I need to change?
The 2017 F-150 uses a “lifetime” fuel filter that is integrated into the fuel pump assembly inside the tank. There is no external filter to change. If you have a fuel delivery issue, you likely need to replace the entire pump module.
Final Thoughts on Your F-150 Fuel Capacity
Knowing your 2017 ford f 150 gas tank size is the foundation of being a prepared truck owner. Whether you have the 23-gallon standard or the 36-gallon monster, understanding your range allows you to push your truck to its limits safely.
Always remember to account for the weight of your fuel when calculating payload and never ignore the warning signs of a failing EVAP system. A well-maintained fuel system ensures that your F-150 remains the reliable workhorse it was designed to be.
If you are planning an upgrade or just performing routine checks, take your time and prioritize safety. Your F-150 is a precision machine, and with the right knowledge, you can keep it running smoothly for hundreds of thousands of miles. Stay safe and stay fueled up!
