The Toyota Tundra is a popular truck model that has been in production since 1995. Some Tundra owners have expressed dissatisfaction with the standard 26-gallon fuel tank, opting instead for an upgrade to the 38-gallon tank. It appears that the 38-gallon tank was first introduced as an option for the 2014 Tundra models, and in 2016, it was included in the SR5 Upgrade Package for models with the 5.7L engine. However, some sources suggest that the 38-gallon tank may not have been standard on all 2016 models, and it is recommended to confirm the fuel tank capacity by checking the mileage range or using the Vehicle Identification Number (VIN) on the Toyota website. Upgrading to the larger fuel tank provides increased range, but it also adds weight to the vehicle, and the cost of filling up a larger tank can be a consideration.

The 2016 SR5 model has a 38-gallon fuel tank upgrade
The 2016 Toyota Tundra SR5 model has a 38-gallon fuel tank upgrade. This is a notable feature of the vehicle, providing an increased fuel capacity compared to the standard 26-gallon tank found in other Tundra models.
The 38-gallon fuel tank was introduced as an upgrade option for the 2016 Tundra SR5, enhancing its fuel capacity and extending its driving range. This upgrade is part of the SR5 upgrade package, which includes additional features such as a console instead of a bench seat. The larger fuel tank offers several benefits to drivers, including fewer refuelling stops and greater flexibility in choosing when and where to refuel.
Upgrading to a larger fuel tank can be a significant advantage for those who frequently embark on long-distance trips or those who prefer the convenience of less frequent refuelling. With the 38-gallon tank, drivers can travel farther between fill-ups, reducing the need to plan fuel stops along their journey. This upgrade is particularly useful for areas where fuel stations may be scarce or for those who wish to avoid the inconvenience of constantly monitoring their fuel level.
The 2016 Tundra SR5 with the 38-gallon fuel tank provides peace of mind and improved fuel management. Owners can enjoy longer intervals between refuelling, which can be especially beneficial when travelling through regions with limited access to fuel stations. Additionally, the increased fuel capacity can lead to cost savings, as drivers can take advantage of more affordable fuel options outside of expensive areas.
While the 38-gallon fuel tank offers enhanced fuel capacity, it is important to consider the associated costs and weight implications. Upgrading to a larger fuel tank may come at a higher price, and the additional fuel weight can impact the vehicle's overall performance and handling. However, for those seeking greater fuel efficiency and the convenience of extended driving ranges, the 2016 Tundra SR5 with the 38-gallon fuel tank upgrade can be an attractive option.

The 2017 SR5 Upgrade Package included a 38-gallon tank
The 38-gallon tank option was introduced by Toyota as early as 2014, according to some sources. However, it was in 2016 that the larger tank became more widely available as an upgrade option for the SR5 model. This upgrade package also included other features such as bucket seats, a console instead of a bench seat, and other convenience features.
The inclusion of the larger tank in the 2017 SR5 Upgrade Package is confirmed by several owners of this particular Tundra model. They have verified that their vehicles are equipped with the 38-gallon tank. This confirmation is supported by the fact that Toyota allows users to verify their vehicle's factory features by punching in the VIN# on the official website.
It is worth noting that not all 2017 SR5 models came with the larger tank. Some owners have reported having the standard 26-gallon tank in their trucks. Additionally, there seem to be conflicting reports about the accuracy of using the front seat configuration to determine the tank size. While some owners suggest that having bucket seats indicates the presence of the larger tank, others have found this method unreliable.
The 2017 SR5 Upgrade Package with the 38-gallon tank offered by Toyota provided a notable enhancement to the vehicle's fuel capacity. This option gave drivers the advantage of extended driving ranges and fewer refuelling stops. However, it is always recommended to refer to official sources and verify specific vehicle features with authorized dealerships to ensure accurate information.

The 2018 model has a 38-gallon tank option
The Toyota Tundra is a popular truck model that has been in production since 1995. While the Tundra is generally well-regarded, one common complaint is its relatively small factory fuel tank, which has a capacity of just 26 gallons. This can be particularly inconvenient for those who wish to purchase fuel at a specific location, rather than simply stopping at the nearest gas station when their tank is close to empty.
In response to this criticism, Toyota began offering a larger, 38-gallon fuel tank as an option for certain Tundra models. While there is some debate about which model year was the first to offer this upgrade, several sources indicate that it became available starting with the 2016 model year. Specifically, it appears that the 38-gallon tank was included as part of the SR5 upgrade package for 2016 Tundras with the 5.7L engine.
However, it is worth noting that not all 2016 Tundras came equipped with the larger tank. Some sources suggest that only the Limited model Crewmax variants featured the 38-gallon tank as standard equipment, while others indicate that it was also available on lower trim levels as part of an optional upgrade package.
For those who own older Tundras or who were unable to purchase a model with the larger tank, it is possible to replace the factory 26-gallon tank with an aftermarket 38-gallon tank. However, this modification can be costly and may require welding and other fabrication work. Additionally, there have been reports of issues with the anti-roll valve getting stuck on some aftermarket 38-gallon tanks, so potential buyers should exercise caution and thoroughly research their options before making any purchases.
Overall, the availability of the 38-gallon fuel tank, either as a factory option or as an aftermarket upgrade, is a welcome development for many Tundra owners. With this larger tank, drivers can enjoy increased range and the freedom to purchase fuel at their preferred locations, rather than being limited to filling up whenever their smaller tank happens to be running low.

The Toyota Tundra is a popular truck model, known for its power and performance. Over the years, various iterations of the Tundra have been released, with different features and specifications. One aspect that has been a focus of attention and discussion among car enthusiasts is the fuel tank capacity.
The introduction of the 38-gallon tank in the 2014 Tundra addressed a common concern among previous Tundra owners, who found the smaller 26-gallon tank limiting in terms of range. With the larger tank, drivers could enjoy greater flexibility and peace of mind, no longer needing to plan fuel stops as frequently or worry about finding a gas station in remote locations.
However, it's worth noting that some owners of the 2014 Tundra with the 38-gallon tank have reported a few drawbacks. One issue mentioned is the increased weight of the larger fuel tank, which can affect the overall handling and fuel efficiency of the vehicle. Additionally, some owners have encountered problems with the anti-roll valve getting stuck, requiring repairs or replacements.
Despite these reported issues, the 2014 Tundra with the 38-gallon fuel tank remains a sought-after model, offering a balance between extended range and driving performance. For those considering an upgrade from the standard 26-gallon tank, the 2014 model year serves as a benchmark, providing the first opportunity to experience the benefits of a larger fuel capacity.

The 38-gallon tank is a factory option
The 38-gallon fuel tank is a factory option for the Toyota Tundra. This option was introduced in 2014, but it was only available for certain models. For example, in 2016, the 38-gallon tank was included in the SR5 Upgrade Package for the SR5 model. This package also included features such as a console instead of a bench seat.

However, one user with a 2018 1794 edition Crewmax model has contradicted this claim, stating that their vehicle only has a 26-gallon tank.
