by Samuel Gitukui

What is the 2021 F150 Gas Tank Size?

The 2021 Ford F150 gas tank size has a fuel tank capacity of 26 gallons. This is the same size as the 2020 model, and it is designed to provide drivers with an extended range between fill-ups. The F150 also features a capless fuel filler system that makes refueling easier and more convenient than ever before.

How Does the 2021 F150 Gas Tank Size Compare to Previous Models?

The 2021 Ford F150 has a larger gas tank size than previous models. The 2021 model features a 36-gallon fuel tank, which is an increase of 6 gallons from the 30-gallon fuel tank found in the 2020 model.

This increase in capacity allows for more miles between fill-ups and fewer trips to the pump. Additionally, this larger gas tank size helps to reduce emissions by allowing drivers to travel further on one full tank of fuel.

The increased capacity also provides greater convenience for those who need to drive long distances or frequently refuel their vehicles. And if you need to learn more about maintaining your Ford F-150, check out our guides below:

What Are the Benefits of a Larger Gas Tank in a 2021 F150?

The 2021 Ford F150 offers a variety of benefits for drivers, including the option of a larger gas tank. A larger gas tank can provide several advantages to drivers, such as increased fuel efficiency and fewer trips to the pump.

  • One benefit of having a larger gas tank is improved fuel economy. With more fuel capacity, you can drive farther on each fill-up and reduce your overall cost per mile.
  • This means that you will be able to save money on gasoline over time by not having to refuel as often. Additionally, with less frequent stops at the pump, you will have more time available for other activities or errands during your travels.
  • Another advantage of having a bigger gas tank is increased range between fill-ups. This allows you to travel longer distances without needing to stop for refueling or worry about running out of fuel in remote areas where there may not be any nearby service stations or convenience stores with gasoline available for purchase.

  • Finally, having a larger gas tank also provides peace of mind when it comes to safety and security while driving long distances in unfamiliar areas or during inclement weather conditions such as heavy rain or snowfall that could make it difficult or impossible to find an open service station along your route if needed due to low visibility conditions caused by foggy windows from condensation buildup inside the vehicle cabin due lack air circulation from outside air entering through open windows while driving at high speeds on highways and interstates which could lead potentially dangerous situations if one were forced into making an emergency stop due running out of fuel before reaching their destination safely.

How Can You Maximize Fuel Efficiency with a Larger Gas Tank in Your 2021 F150?

Fuel efficiency can be maximized with a larger gas tank in your 2021 F150 by following a few simple steps.

  1. First, make sure to keep your tires properly inflated. Underinflated tires can reduce fuel economy by up to 3%. Check the pressure regularly and adjust as needed. If you need to find more resources, check out our list of the best portable air compressor for truck tires.
  2. Second, use cruise control whenever possible. Cruise control helps maintain a steady speed which reduces fuel consumption and increases efficiency.
  3. Third, avoid aggressive driving habits such as rapid acceleration or hard braking as this will decrease fuel economy significantly. Instead, accelerate gradually and brake gently when possible to maximize efficiency.
  4. Fourth, minimize the use of air conditioning when driving at lower speeds or on shorter trips; open windows instead if necessary for ventilation purposes while still maintaining an aerodynamic shape for the vehicle body that will help improve fuel economy overall.
  5. Finally, consider investing in an aftermarket larger gas tank for your 2021 F150 that is designed specifically for increased capacity and improved performance; this will allow you to travel further distances without having to refuel as often which can save money on gasoline costs over time while also increasing overall fuel efficiency of the vehicle itself.

Is It Worth Upgrading to a Larger Capacity Fuel Tank for Your 2021 F150?

The 2021 Ford F150 is a powerful and reliable truck that offers plenty of features to make your driving experience more enjoyable.

However, one area where the F150 may be lacking is in its fuel capacity. The standard tank size for the 2021 model is 23 gallons, which can limit how far you can travel before needing to refuel.

If you are looking for a way to extend your range on long trips or just want more peace of mind when it comes to fuel availability, then upgrading to a larger capacity fuel tank may be worth considering.

Larger tanks are available from aftermarket suppliers and offer up to 40 gallons of additional storage space for gasoline or diesel fuels.

This extra capacity could potentially double the distance you can travel before needing a refill, giving you greater flexibility when planning longer journeys or hauling heavier loads.

In addition, larger tanks also provide an extra layer of protection against running out of gas in remote areas where there may not be any nearby fueling stations available. This could save time and money by avoiding costly tows back home due to an empty tank situation.

Overall, upgrading your 2021 Ford F150 with a larger capacity fuel tank could prove beneficial if you frequently take long trips or need extra assurance that there will always be enough gas in the tank when needed most.

What Are Some Tips for Maintaining and Caring for Your 2021 F150’s Fuel System?

1. Regularly check the fuel filter for any signs of dirt or debris that could clog the system and reduce fuel efficiency. Replace it as needed.

2. Make sure to use only high-quality gasoline in your 2021 F150, as this will help keep your engine running smoothly and efficiently over time.

3. Keep an eye on the fuel level in your tank, especially when you’re driving long distances or carrying heavy loads, as this can affect how much gas is used up quickly and cause you to run out of gas unexpectedly if not monitored closely enough.

4. Have a professional inspect the fuel system at least once a year to ensure everything is working properly and there are no leaks or other issues that could lead to costly repairs down the line if left unchecked for too long.

5. Make sure all hoses connected to the tank are securely fastened so they don’t come loose while driving, which can cause dangerous spills onto hot engine parts or even start a fire if not taken care of immediately after noticing it has happened.

How Can You Tell If You Need to Replace or Upgrade Your Current Fuel System?

If you are considering upgrading or replacing your current fuel system on your 2021 F150 to accommodate a larger capacity gas tank, there are several factors to consider.

First, you should check the manufacturer’s specifications for the vehicle and determine if it is capable of supporting a larger capacity gas tank. If not, then an upgrade or replacement may be necessary.

Additionally, you should inspect the existing fuel system components such as hoses and lines for signs of wear or damage that could affect their ability to support a larger capacity tank.

Finally, if any modifications need to be made to install the new tank safely and securely, these must also be taken into account when determining whether an upgrade or replacement is necessary.

What Are The Pros And Cons Of Installing A Bigger Capacity Fuel tank?

The installation of a larger capacity fuel tank on a newer model year Ford truck such as the 2020 or 2021 F-150 can be beneficial in certain situations, but it also has some drawbacks.


Increased range – A larger fuel tank will allow you to travel further without having to refuel, which is especially useful for long trips.

Improved efficiency – With more fuel available, your engine will run more efficiently and use less gas overall. This can help save money on gas costs over time.

Reduced emissions – By using less gasoline overall, you’ll be reducing your carbon footprint and helping the environment by emitting fewer pollutants into the atmosphere.


Cost – Installing a bigger capacity fuel tank may require additional parts and labor that could add up quickly depending on the size of the tank being installed.

Weight – The added weight of a larger capacity fuel tank could affect performance and handling if not properly balanced with other components such as suspension or tires.

Space constraints – Depending on where you plan to install it, there may not be enough room for a bigger capacity fuel tank due to space constraints in certain areas of your vehicle’s frame or bodywork
