What You'll Learn
The standard Jeep Gladiator fuel tank capacity is 22 gallons
The standard fuel tank capacity of the Jeep Gladiator is 22 gallons. This information is available on the build sheet of the vehicle. The low fuel light is supposed to come on and chime when there are 2 gallons left in the tank.
Some Jeep Gladiator owners have reported discrepancies between the advertised fuel tank capacity and their own calculations based on fuel fill-ups. For example, one owner filled up their Gladiator at the quarter-tank mark and it only took 10.5 gallons, which would indicate a total capacity of less than 22 gallons. Another owner filled up their tank from empty to full and it only took 16.5 gallons, which is significantly less than the advertised 22 gallons.
It's important to note that there may be some variances or error margins in the fuel tank capacity. As one engineer explained, if the tank is made to hold 22 gallons with a possible variance of 1 gallon, that's an accepted variance of 4.5%. Additionally, the fuel pump itself may have an accuracy range of 3-5%, depending on the difficulties of measuring fluids in motion. These factors can contribute to discrepancies in the estimated fuel tank capacity.
To enhance the vehicle's range, some Gladiator owners have opted to install auxiliary fuel tanks. These auxiliary tanks can add 17 gallons of capacity, increasing the total fuel capacity to 39 gallons. However, it's recommended that the installation of these auxiliary tanks be undertaken by experienced and well-equipped workshops.

The low fuel light comes on at 2 gallons remaining
The Jeep Gladiator is advertised as having a 22-gallon fuel tank. However, some owners have reported discrepancies between this number and the amount of fuel required to fill up their tanks. For example, one owner filled up their tank at a quarter full, which should have required around six gallons of fuel, but it only took 10.5 gallons. Another owner reported that their tank was supposedly full after just 16.5 gallons, despite the gas light being on.
These discrepancies could be due to several factors, including variances in manufacturing, the fuel pump's accuracy, and the difficulties of measuring fluids in motion. It's also possible that the fuel gauge is faulty or that the tank is not being filled to its actual capacity.
To ensure the accuracy of the fuel gauge, it is recommended to fill up the tank closer to the 1/4 mark, as this will reduce the potential for error and be healthier for the fuel pump. Running the tank down to empty is not advisable, as it can lead to pump failure and is generally unhealthy for the vehicle.
The low fuel light on the Jeep Gladiator is designed to come on when there are two gallons of fuel remaining in the tank. This feature is intended to prevent drivers from running out of fuel and potentially stranding themselves. However, some owners have reported that the low fuel light did not come on, even when they believed they had less than two gallons of fuel left.
In conclusion, while the Jeep Gladiator is advertised as having a 22-gallon fuel tank, there may be some variability in the actual tank size or the accuracy of the fuel gauge. To maintain optimal performance and avoid potential issues, it is recommended to fill up the tank before it reaches the empty mark and to pay attention to the low fuel light as a precautionary measure.

The fuel gauge may be inaccurate, showing more range than is actually available
The Jeep Gladiator is advertised as having a 22-gallon fuel tank. However, some owners have reported discrepancies between the amount of fuel they put in and what would be expected for a 22-gallon tank. For example, one owner filled up their tank from a quarter full, and it only took 10.5 gallons, which would mean their tank only held 14 gallons. Another owner filled their tank from empty to full and only filled 16.5 gallons, despite their build sheet saying they had a 22-gallon tank with 4 extra gallons.
These discrepancies could be due to a variety of factors, including variances in manufacturing, the way fuel is measured, and the design of the fuel pump. It's also possible that the fuel gauge in some vehicles is inaccurate, showing more range than is actually available. This could be due to conservative programming that reports the tank as empty before it actually is to prevent the vehicle from running out of fuel and straining the fuel pump.
Some owners have found that their low fuel light comes on when they still have several gallons of fuel left. For example, one owner reported that their low fuel light came on when they had over 4 gallons left, rendering their supposed 22-gallon tank into an 18-gallon one. Another owner had a similar experience, with their low fuel light coming on when they still had over 2 gallons left.
These discrepancies can be frustrating for owners who want to know exactly how much fuel they have left and how far they can go before needing to refuel. While it's understandable that Jeep would want to err on the side of caution to prevent fuel pump issues, some owners feel that the conservative programming is too extreme and would prefer a more accurate estimate of their range.
To address this issue, some owners have opted to install a long-range auxiliary fuel tank, which can extend the vehicle's range and provide a more accurate estimate of the remaining fuel. These replacement tanks tend to hang on full for a while, and the low fuel warning lights generally come on at the same level as the original tank, but with a greater reserve capacity. However, modifying the fuel tank system is not a simple task and should be undertaken by experienced professionals to ensure safety and proper installation.

Running the tank down is not healthy for the fuel pump
The Jeep Gladiator has a 22-gallon fuel tank. However, some sources suggest that the vehicle can accommodate a 17-gallon auxiliary fuel tank, increasing the total capacity to 39 gallons.
Now, while some people believe that running the tank down is not an issue due to the presence of strainers and filters in modern fuel systems, others argue that it can be detrimental to the fuel pump's health. Here are some reasons why letting your Jeep Gladiator's fuel tank run down is not advisable:
First and foremost, fuel acts as a coolant for the electric motor of the fuel pump. When the tank is empty, the pump will draw in air, leading to overheating and potential damage or reduced service life. This is because the pump is designed to be submerged in fuel, which not only cools it but also lubricates it. Running the tank down can cause the pump to overwork, generating heat and potentially shortening its lifespan.
Additionally, while modern fuel systems have strainers and filters to prevent sediment from entering the pump, running the tank down increases the risk of sediment buildup, which can negatively impact the pump's performance.
Moreover, the margin for error in fuel gauge readings should be considered. The Jeep Gladiator's fuel gauge may not always provide an accurate representation of the actual fuel level. Running the tank down increases the chances of unexpectedly running out of fuel, which can be unsafe and inconvenient.
To summarise, while it may not be catastrophic to occasionally run your Jeep Gladiator's fuel tank down, it is advisable to refuel before reaching extremely low levels. Maintaining a quarter tank or more can help ensure the fuel pump remains lubricated, cooled, and free from sediment buildup, prolonging its lifespan and optimising performance.
