The Chevrolet Colorado is a versatile midsize pickup truck. In 2017, General Motors (GM) introduced a capless fuel system for the Colorado and GMC Canyon. This change has divided opinions, with some praising the improved seal that keeps water and dirt out of the fuel tank, while others express concerns about the lack of a locking fuel door, which could potentially allow vandals to tamper with the tank.

What You'll Learn
Benefits of the capless system
The capless system in the Chevrolet Colorado has several benefits. Firstly, it prevents water, dirt, dust, and debris from entering the fuel tank, ensuring a clean fuel supply and optimal engine performance. This is achieved through a good seal mechanism, which also makes it harder for someone to siphon fuel or tamper with the tank. Secondly, there is no fuel cap to dangle and potentially scratch the vehicle's painted surfaces during refueling. The absence of a cap also eliminates the risk of forgetting to close the cap after refueling, which can lead to fuel evaporation or spillage.
While some users of the capless system in the Chevrolet Colorado have expressed concerns about dust buildup, others have shared their experiences with no issues. The capless system is designed to be convenient and efficient, and it is essential to follow the proper refueling procedures, such as waiting a few seconds after refueling before removing the nozzle and closing the fuel door.
The capless system also offers improved security. While the fuel door may not have a lock, the mechanisms in the fuel filler neck make it challenging to siphon more than a few gallons of gas, deterring potential fuel theft.
Overall, the capless system in the Chevrolet Colorado offers several advantages, including enhanced fuel tank protection, convenience, and security. While some users have expressed mixed opinions, following the recommended refueling procedures can help ensure a positive experience with the capless system.

Issues with the capless system
The capless fuel system in the Chevrolet Colorado is a convenience technology introduced by General Motors to make fuelling a vehicle more convenient. Instead of a traditional twist-off gas cap, the system uses a set of two doors, each locking fuel in with a rubber seal around its edge.
While the capless system offers benefits such as preventing scratches on painted surfaces and making it harder to siphon fuel, there have been some issues reported by users:
- Some users have reported that the capless system can get stuck when trying to refuel, requiring the use of a long funnel to add fuel.
- There are concerns about dirt, dust, and debris getting into the fuel tank through the capless filler. While some users have reported no issues, others believe that over time, dust and debris can enter the filler and cause problems.
- There are mixed reviews about the ease of use of the capless system. Some users find it challenging to remove, especially during the winter, while others have no issues.
- One user reported that the rubber seal on the gas cap and holder looked 3D printed and expressed concerns about its durability.
- Another issue reported is the potential for overfilling the fuel tank, which may cause performance issues, fuel spills, or potential fuel fires. It is recommended to wait a few seconds after refuelling before removing the nozzle and closing the fuel door.

Comparison to the traditional cap
The capless fuel system has several advantages over the traditional capped system. Firstly, there is no dangling fuel cap that could scratch painted surfaces while refuelling, and there is no cap that could be forgotten and left open when driving off. The capless system also makes it nearly impossible to siphon more than a few gallons of gas, improving security.
Additionally, the capless system is more convenient and foolproof. There is no gas cap to deal with, and the risk of issues like stuck nozzles or fuel cutting off, which are common with capped systems, is reduced. The spring-loaded closure in the capless system seals the tank when the pump nozzle is removed, preventing fuel and vapours from escaping.
However, some users have expressed concerns about the capless system. One issue is the potential for dirt and dust to enter the gas tank, especially when driving on dirt roads or off-road. While a double flap system and fuel door aim to prevent this, some users still opt for additional covers. Another concern is the difficulty of refuelling with a portable fuel container, which requires a special tool and knowledge of the system.
Overall, the capless fuel system offers benefits such as improved security, convenience, and reduced risk of fuel evaporation, but it may require adjustments in certain driving conditions and refuelling situations.

How to use a capless fuel filler
Filling up a vehicle with a capless fuel system is a straightforward process. To use a capless fuel filler, simply open the fuel door and insert the pump nozzle. When fuelling is complete, removing the nozzle will cause the spring-loaded fuel filler to close and latch, sealing the tank and preventing fuel and vapours from escaping.
It is important to note that overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause performance issues, fuel spills, or potential fuel fires. Therefore, it is recommended to wait a few seconds after refuelling is complete before removing the nozzle and closing the fuel door.
If you need to add fuel from a portable gas can, you will need to locate the capless funnel adapter, which is typically found in the trunk of a car, truck, or SUV, and under the rear seat in a pickup truck. Insert and latch the funnel into the capless fuel system, then remove and clean the funnel adapter before returning it to its storage location.
The capless fuel filler system offers several benefits, including the elimination of a dangling fuel cap that could scratch painted surfaces, and the reduced risk of fuel theft or vapours escaping into the atmosphere. Additionally, the design of the fuel filler neck makes it challenging to siphon more than a few gallons of gas.

Capless fuel filler on other vehicles
Capless fuel filler systems are becoming increasingly common in modern vehicles. Ford was one of the first to introduce this technology, making it standard on the 2009 Explorer SUV and Mercury Mountaineer. Since then, Ford has expanded its use of capless fuel fillers to other models, including the 2009 Ford F-150 pickup truck and the Ford Flex and Lincoln MKS SUVs. The system features a spring-loaded flap that automatically latches shut, eliminating the need for a fuel filler cap.
Several other automakers have followed Ford's lead and now offer capless fuel fillers on their vehicles. This includes General Motors brands such as Cadillac, Chevrolet, and GMC. The Cadillac Escalade and Chevrolet Blazer SUVs, as well as the Malibu sedan and the GMC Canyon and Sierra pickup trucks, are offered with capless fuel filler technology. Honda has also adopted capless fuel fillers, with the feature available on the Honda Passport SUV. Fiat Chrysler and other automakers are also incorporating capless fuel fillers into their vehicles.
The benefits of capless fuel fillers include increased convenience, as there is no fuel cap to remove and replace during refuelling. This also reduces the risk of forgetting to replace the cap or leaving it on the car roof while driving. Capless systems can help prevent fuel spills, splashback, and fuel theft. Additionally, they can reduce the escape of fuel vapours into the atmosphere and minimise the amount of fuel smell that gets on your hands during refuelling.
However, there are also some potential drawbacks to capless fuel fillers. One issue is the need for a special funnel when refuelling from a portable gas can. The funnel can be cumbersome to store and may retain a strong fuel smell. Overfilling the tank can also be problematic, potentially leading to performance issues, fuel spills, or even fuel fires. It is important to wait a few seconds after refuelling before removing the nozzle and closing the fuel door to avoid these issues.
