At EngineNeeds, we understand that your truck is more than just a vehicle—it’s a partner in work and play. This comprehensive guide will equip you with everything you need to know about the 2017 Ford F-150 tank size, helping you master your truck’s capabilities and confidently tackle whatever lies ahead.

Understanding Your 2017 Ford F-150 Tank Size Options

The 2017 Ford F-150, known for its versatility and robust performance, came with several fuel tank options to cater to different needs and configurations. Ford recognized that a daily commuter has different demands than someone regularly towing a fifth-wheel camper or heading deep into the backcountry. Therefore, they offered a range of capacities.

The standard fuel tank for most 2017 F-150 models was a 23-gallon unit. This size provided a respectable range for everyday driving and lighter tasks. However, for those who needed more endurance, Ford offered larger options.

A popular upgrade, especially for SuperCrew and SuperCab configurations, was the 36-gallon extended range fuel tank. This significantly larger tank provided a substantial boost in driving range, reducing the frequency of fuel stops and making it ideal for long-haul journeys or extended periods off the beaten path.

It’s important to note that the specific tank size often depended on the truck’s configuration, including its cab style (Regular Cab, SuperCab, SuperCrew) and bed length (5.5 ft, 6.5 ft, 8 ft). While the 23-gallon tank was common, the 36-gallon option was a game-changer for many owners.

Decoding Your F-150’s Fuel Capacity by Configuration

To pinpoint your specific 2017 Ford F-150 tank size, it’s helpful to consider the original build. Certain combinations of cab and bed length were more likely to have the larger fuel tank as an option, or even as standard in some higher trims.

  • Regular Cab: Often came with the 23-gallon tank. The larger tank was less common due to packaging constraints and the typical use case for a Regular Cab.
  • SuperCab: Could be found with both the 23-gallon and the optional 36-gallon tank. This depended heavily on trim level and specific option packages.
  • SuperCrew: This is where the 36-gallon extended range tank really shined. Many SuperCrew models, especially with longer beds (6.5 ft), were equipped with or offered the 36-gallon tank as a highly desirable option.

Checking your truck’s original window sticker or owner’s manual is the most accurate way to confirm its factory-installed fuel tank capacity. If those aren’t available, look for a label near the fuel filler neck or consult a Ford dealership with your VIN.

Real-World Impact of Your Fuel Tank Capacity

Understanding your 2017 Ford F-150 tank size goes beyond just a number; it dictates your truck’s practical range and affects how you plan trips, budget for fuel, and even approach off-road adventures. A larger tank offers significant advantages, but it also comes with a few considerations.

Calculating Your Driving Range

To estimate your truck’s driving range, you’ll need two pieces of information: your fuel tank size and your average miles per gallon (MPG). While the EPA provides estimated MPG figures, your real-world MPG will vary based on driving habits, terrain, cargo weight, and whether you’re towing.

A simple formula is: Tank Size (gallons) x Average MPG = Estimated Driving Range (miles)

For example, a 2017 F-150 with a 3.5L EcoBoost engine might average around 18 MPG combined. With a 23-gallon tank, your range would be approximately 414 miles. With the 36-gallon tank, that jumps to around 648 miles! This extra range is a huge benefit for long-distance travel.

Fuel Economy and Towing Considerations

Towing significantly impacts fuel economy. When hauling a heavy trailer, your MPG can drop by 30-50% or even more, depending on the load and terrain. This drastically reduces your effective driving range.

For instance, if your 3.5L EcoBoost F-150 typically gets 18 MPG but drops to 10 MPG while towing a travel trailer:

  • 23-gallon tank: Range drops from 414 miles to approximately 230 miles while towing.
  • 36-gallon tank: Range drops from 648 miles to approximately 360 miles while towing.

This difference highlights why the larger 2017 Ford F-150 tank size is often preferred by those who regularly tow. It means fewer stressful stops and more uninterrupted travel.

Upgrading Your 2017 F-150’s Fuel Capacity

If your 2017 F-150 came with the smaller 23-gallon tank, and you frequently find yourself wishing for more range, you’re not alone. Many owners consider upgrading to a larger capacity. This can involve swapping the factory tank or adding an auxiliary fuel system.

Factory Tank Swap: Is It Possible?

Swapping a 23-gallon tank for a factory 36-gallon unit is a common modification. It’s often a direct bolt-on replacement, as the frame rails and mounting points are generally the same across different F-150 configurations that supported both tank sizes. However, there are a few considerations:

  • Fuel Pump Assembly: You may need to transfer your existing fuel pump assembly to the new tank, or purchase a new one if yours is aging.
  • Straps and Shield: The longer 36-gallon tank will require longer mounting straps and potentially a different heat shield.
  • Fuel Gauge Calibration: In most cases, the truck’s computer (PCM) automatically recognizes the larger tank size once installed and recalibrates the fuel gauge. However, some older models or specific trim levels might require a visit to a Ford dealership for a software update. It’s best to research this for your specific truck.
  • Cost: A new OEM 36-gallon tank can be costly, but used tanks from salvage yards are often available at a more reasonable price.

This DIY project is manageable for experienced mechanics, but it does involve working with flammable liquids. Always ensure proper safety precautions, including disconnecting the battery, working in a well-ventilated area, and having a fire extinguisher nearby.

Auxiliary Fuel Tanks for Extreme Range

For off-roaders, overlanders, or those embarking on truly remote expeditions, even the 36-gallon tank might not be enough. This is where aftermarket auxiliary fuel tanks come into play. These are additional tanks installed in the truck bed or underneath the vehicle, plumbed into the main fuel system.

Types of Auxiliary Tanks:

  • In-Bed Transfer Tanks: These sit in the truck bed and often include a pump to transfer fuel to the main tank as needed. They are generally easier to install but consume valuable bed space.
  • Under-Vehicle Auxiliary Tanks: These are custom-fit tanks that replace a spare tire location or fit into other unused spaces beneath the truck. They are more complex to install but keep the bed free.

When considering an auxiliary tank, research reputable brands that offer robust construction and proper baffling to prevent fuel sloshing. Ensure the installation adheres to all local regulations and safety standards. Always consult with a professional if you’re unsure about the installation process, especially when dealing with fuel lines and electrical connections.

Maintenance and Safety for Your F-150’s Fuel System

Regardless of your 2017 Ford F-150 tank size, proper maintenance of your fuel system is critical for performance, reliability, and safety. Neglecting this vital component can lead to costly repairs and even dangerous situations.

Regular Fuel System Checks

Keep an eye on these key components:

  • Fuel Filter: The fuel filter prevents contaminants from reaching your engine. Consult your owner’s manual for recommended replacement intervals, which can vary but are often every 20,000-30,000 miles. A clogged filter can lead to reduced fuel economy, loss of power, and even engine stalling.
  • Fuel Lines and Hoses: Periodically inspect fuel lines and hoses for cracks, leaks, or signs of wear. Look for any weeping fuel or strong gasoline odors. Replace any damaged components immediately.
  • Fuel Cap: A properly sealing fuel cap is crucial for maintaining fuel system pressure and preventing evaporative emissions. A loose or faulty cap can trigger a “Check Engine” light.
  • Fuel Tank Straps: Ensure the straps holding your fuel tank in place are secure and free from corrosion.

Safety First When Working with Fuel

Working with gasoline requires extreme caution:

  1. Work in a Well-Ventilated Area: Gasoline fumes are highly flammable and can be toxic.
  2. No Open Flames or Sparks: This includes cigarettes, grinders, or anything that can ignite fuel vapors.
  3. Disconnect the Battery: Before working on any fuel system components, disconnect the negative terminal of your truck’s battery to prevent accidental electrical sparks.
  4. Have a Fire Extinguisher Handy: A Class B or ABC fire extinguisher should always be within reach.
  5. Wear Proper PPE: Gloves and eye protection are essential to protect against fuel splashes and contact.
  6. Manage Spills: Have absorbent materials ready to clean up any fuel spills immediately. Dispose of contaminated materials properly.

Maximizing Range and Fuel Efficiency

Having a large 2017 Ford F-150 tank size is great, but getting the most out of every gallon is even better. Here are some tips to maximize your range and improve fuel efficiency:

  • Maintain Proper Tire Pressure: Underinflated tires increase rolling resistance, forcing your engine to work harder and consume more fuel. Check your tire pressure regularly, especially before long trips.
  • Drive Smoothly: Avoid aggressive acceleration and hard braking. Smooth, consistent driving uses less fuel. Utilize cruise control on highways.
  • Reduce Excess Weight: Remove unnecessary items from your truck bed or cab. Every extra pound reduces fuel efficiency.
  • Aerodynamics Matter: If you have a tonneau cover, keep it closed. Remove roof racks or bed racks when not in use, as they create drag.
  • Regular Maintenance: Keep your engine tuned up, air filter clean, and spark plugs in good condition. A well-maintained engine runs more efficiently.
  • Plan Your Routes: Use navigation apps to find the most efficient routes, avoiding heavy traffic and unnecessary detours.
  • Fuel Quality: Use reputable gas stations and the octane level recommended by Ford for your engine.

By combining a smart driving approach with a well-maintained truck, you can extend the range of your 2017 F-150 significantly, whether you have the standard or extended-range fuel tank.
