Capless gas tanks are a convenient feature that eliminates the need for a fuel cap and makes refuelling easier. However, they can also pose challenges when it comes to performing basic maintenance, such as adding fuel additives or injector cleaners. The small bottle openings of these additives may not fit directly into the capless fuel tank, requiring the use of a special funnel or tool. This funnel is typically provided by the car manufacturer and can be found in the trunk, cargo bin, or glove box, as mentioned in the owner's manual. It is designed to open both filler neck doors and facilitate the addition of fuel additives or emergency fuel from a portable container. Some manufacturers also offer filler plugs or nozzles of similar size to the fuel nozzle, which can be purchased separately.

What You'll Learn
Using a funnel to add fuel additives
If you want to add fuel additives to your capless gas tank, you will need to use a funnel. Some manufacturers, like Ford and Honda, include a special funnel in the trunk or cargo area of new vehicles with capless technology. These funnels are designed to fit into the fuel filler area of the tank, allowing you to add fuel or additives without triggering the check engine light.
If your vehicle does not come with a funnel, you can purchase one from a dealership or parts centre. The Hopkins Towing Solutions FloTool 10719 Capless Gas Tank Funnel is a popular option that is designed to fit capless and restricted fuel fillers/tanks. It has an easy-grip handle and an on/off spout for accurate pouring and measuring. This funnel also signals when the gas tank is full to prevent spills and overfills.
When choosing a funnel, it is important to consider the size and diameter. The funnel should match the diameter of a gas pump nozzle to open the tank's filler tube inside flap effortlessly. A funnel with a low profile will also make it easier to store but will require slower and more careful pouring.
To use the funnel, simply insert it into the fuel filler area of your capless gas tank. You may need to use a long, narrow metal or plastic tube to disengage the locks/tabs on the spring-loaded door first. Once the funnel is in place, you can slowly and carefully pour your fuel additive into the tank.

Using a tube to disengage locks/tabs
If you want to add fuel to a capless gas tank, you can use a tube to disengage the locks/tabs on the spring-loaded door. This method is useful if you want to add additives to your gas or fill up your tank using a gas can.
Firstly, you need to find a long, narrow metal or plastic tube with the same diameter as the nozzle. This tube will be used to disengage the locks/tabs. You can find these tubes at Ford dealerships or parts centres for around $30. Alternatively, some car manufacturers like Honda and Ford provide a special funnel in the car's trunk or under-floor cargo area.
Once you have the tube, insert it into the fuel filler area to disengage the locks/tabs. This will allow you to open the flappers that prevent fuel from spilling out while driving. After the locks/tabs are disengaged, you can use a small funnel to add fuel or additives to your tank.
It is important to note that not all funnels will press both tabs, so you may need to purchase a specialty funnel. These funnels are designed to work with capless gas tanks and can be found at gas stations or ordered online for $2 to $18.
When using a funnel, always take precautions to avoid spilling gas, as it can pose a fire hazard. Make sure to clean up any spilled gas before starting your car.

Finding the special tool in your vehicle
Filling up a vehicle with a capless fuel system is generally straightforward. You simply open the fuel door and insert the pump nozzle. However, if you run out of fuel and need to top up your vehicle using a portable fuel container, you will need to use a special tool to avoid damaging the capless fuel system.
This special tool is usually a funnel provided by the manufacturer, which needs to be inserted into the fuel filler area before adding emergency fuel. Some manufacturers, such as Honda and Ford, include this funnel with the vehicle. In newer Honda models, the funnel is placed in the under-floor cargo area, making it easily accessible. In Ford vehicles, the funnel can be found in the trunk.
However, in some models, the funnel may be hidden behind a panel or in a less obvious location. If you are unsure where to find the special tool in your vehicle, there are several steps you can take. First, check your vehicle's manual, either online or in the printed version, under keywords such as "Capless Fuel," "Tools," or "Refueling." If you cannot find the information in the manual, try searching online by including the year and model of your vehicle along with the keywords "capless fuel filler."
Additionally, some vehicle owners have shared their experiences and knowledge on online forums and discussion boards. These can be a valuable source of information for locating the special tool in your specific vehicle model. It is important to locate the capless fuel filler tool and ensure it is easily accessible when needed. Remember to also inform others who use your vehicle about the location of the tool.

Using the correct nozzle size
When adding fuel to a capless gas tank, it is important to use the correct nozzle size. This is because the capless fuel tank has a spring-loaded flapper that can only be released when a fuel nozzle of a specific size is placed inside. Using the wrong nozzle size can cause issues and may even damage the fuel tank.
The correct nozzle size for your capless gas tank will vary depending on the vehicle's make and model. It is important to refer to the vehicle's owner's manual to determine the correct nozzle size. In some cases, the manual may specify a particular type or brand of nozzle that is compatible with the gas tank. It is important to follow these specifications to ensure safe and proper fuelling.
Additionally, some vehicles may come with a special funnel designed specifically for their capless fuel system. For example, Honda and Ford include a special funnel that needs to be inserted into the fuel filler area before adding emergency fuel. This funnel can usually be found in the vehicle's trunk, cargo area, or behind a panel. Referring to the owner's manual can help locate the funnel and provide instructions on how to use it properly.
If you are unable to find the specific nozzle size or the special funnel for your vehicle, there are a few alternatives to consider. Some capless gas tank owners have suggested purchasing a nozzle that is similar in size to the fuel filler opening. This can be done by measuring the diameter of the fuel filler and finding a nozzle that matches those dimensions. It is important to note that using a nozzle that is too large can damage the fuel tank, so it is always best to err on the side of caution and choose a slightly smaller nozzle if you are unsure.
In some cases, a universal funnel or a skinny aftermarket funnel may also be used to add fuel to a capless gas tank. These funnels can be inserted into the fuel filler to guide the fuel flow. However, it is important to avoid funnels with corrugated tubing as they can cause problems inside the fuel filler area. Always choose a smooth, straight funnel that fits securely into the filler neck.

Preventing splashback and fuel vapours
To prevent splashback and fuel vapours when filling up a capless gas tank, there are several methods you can use. Firstly, ensure you have a good seal between the fuel nozzle and your tank so that vapours do not escape. Some gas stations have longer hoses that can be stretched over the top of your car, but this can create a poor seal, allowing gas vapours to escape.
To avoid splashback, it is recommended to go slow and steady when filling up. Angle the nozzle so that it is pointing to the left side of the fill neck, just under the inside end. Using two hands, slowly squeeze the handle to start the flow of fuel. Going slowly will reduce splashing, and it is worth taking your time to avoid fuel splashing onto your car's paintwork.
When the tank is nearly full, ease off on the flow rate to avoid overfilling and causing a spill. Once the pump automatically shuts off, tilt the nozzle downwards and wait for any remaining fuel to drain into the tank. Then, point the nozzle straight up and remove it from the tank to avoid drips.
To limit vapours, keep the gas cap on until you are ready to pump, and stand upwind if possible to avoid breathing in any escaping vapours. After filling up, replace the cap, twisting until you hear a clicking sound to ensure it is on tight. This will help to prevent fuel vapours from escaping and harming the atmosphere.

Frequently asked questions
Capless gas tanks are designed to allow you to simply insert the fuel nozzle until the spring-loaded flapper is released. Once fueling is completed, removing the nozzle will cause the spring-loaded fuel filler to close and latch.
Some capless gas tanks come with a special funnel that needs to be inserted into the fuel filler area before adding fuel. This funnel is usually located in the trunk, cargo bin, or glove box. You can also purchase a nozzle of a similar size or a filler plug from dealerships or parts centers.
The use of a corrugated flexible fuel spot on your portable plastic gas container can cause problems inside the fuel filler area. Failing to use the correct funnel may also result in a "check engine" light, requiring a trip to the dealer for repairs.
