Adding fuel injector cleaner to a capless gas tank can be challenging due to the tank's design, which includes a spring-loaded flapper that only opens for fuel nozzles of a specific size. This security feature, intended to deter fuel theft, can make it difficult for car owners to perform basic maintenance, such as adding fuel additives or stabilizers. However, there are a few methods that can be employed to overcome this issue. One solution is to use a funnel specifically designed for capless fuel tanks, which can be found in the owner's manual or purchased separately. Alternatively, a narrow metal or plastic tube with a diameter similar to the nozzle can be used to disengage the locks/tabs on the spring-loaded door, allowing for the addition of the fuel injector cleaner.

What You'll Learn
Using a funnel to add fuel injector cleaner
First, it's essential to understand why you're using a fuel injector cleaner in the first place. Fuel injectors can become clogged with dirt, carbon deposits, and other impurities over time, leading to reduced fuel efficiency, engine performance issues, and increased emissions. Regular use of a fuel injector cleaner helps mitigate these problems and ensures optimal fuel delivery and combustion, keeping your car running smoothly and efficiently.
Now, let's get into the step-by-step process of using a funnel:
- Choose the Right Cleaner: Select a fuel injector cleaner that is compatible with your car's fuel system. Most cleaners work with gasoline engines, but some are designed specifically for diesel engines. Check your car's manual for recommended brands or types. Read reviews and choose a reputable product.
- Prepare Your Car: Ensure your car is ready for the treatment. It's best to use the fuel injector cleaner when your gas tank is almost empty. This allows the cleaner to mix with the remaining fuel, creating a concentrated solution that maximizes its effectiveness.
- Gather Supplies: You'll need the fuel injector cleaner, a funnel, and possibly some protective gloves. Gloves are recommended to protect your hands from any chemical exposure.
- Open the Fuel Tank: Unscrew the fuel cap of your vehicle. If you have a 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, as some users have suggested. This will allow you to access the filler neck.
- Use the Funnel: Place the funnel into the filler neck or gas tank opening. The funnel helps prevent spillage and directs the cleaner into the tank. Some vehicles may come with a specific funnel that opens both filler neck doors, so check your owner's manual for instructions on using this funnel.
- Pour the Cleaner: Carefully pour the recommended amount of fuel injector cleaner into the funnel. Most cleaners will have a measuring guide on the bottle, so follow the instructions for the proper dosage.
- Fill the Tank: After adding the cleaner, fill up your gas tank with fuel. This helps to mix the cleaner thoroughly with the fuel.
- Replace the Fuel Cap: Once you've added the cleaner and fuel, securely replace the fuel cap.
- Drive Your Vehicle: After treating your fuel system, take your car for a drive. Normal driving conditions are sufficient to circulate the cleaner through the fuel system. If possible, opt for a longer drive to give the cleaner more time to work effectively.
Remember to always handle fuel injector cleaner with care. Avoid ingestion, inhalation of fumes, and direct skin or eye contact. Keep the cleaner away from children and pets, and follow the instructions on the product label for safe use and proper dosage.

Using a tube to disengage locks/tabs on the spring-loaded door
To add a fuel injector cleaner to a capless gas tank, you will need a long, narrow metal or plastic tube with the same diameter as the nozzle. This tube can be used to disengage the locks/tabs on the spring-loaded door of the gas tank.
The spring-loaded door of a capless gas tank is designed to be held closed by latches that can only be released by inserting a standard-size fuel nozzle into the filler neck. This is to deter gas theft and eliminate the need for a fuel tank screw cap. However, when trying to add a fuel injector cleaner with a small bottle, the bottle may not be able to disengage the locks/tabs and open the spring-loaded door.
This is where the tube comes in. By inserting the tube into the filler neck, you can manually disengage the locks/tabs that hold the spring-loaded door closed. It is important that the tube has the same diameter as the nozzle to ensure it fits properly and does not damage the locking mechanism. Once the locks/tabs are disengaged, the spring-loaded door will open, and you can then use a small funnel to pour in the fuel injector cleaner.
It is worth noting that some car models may have two doors in the filler neck, so you may need to use the tube to open both doors before being able to add the fuel injector cleaner. Additionally, always refer to your car's owner's manual for specific instructions on adding fuel additives and using any tools or equipment.

Using a nozzle of similar size to the gas tank
If you have a capless gas tank and are looking to add a fuel injector cleaner, you may encounter some challenges due to the design of the capless system. One effective solution is to use a nozzle of a similar size as the gas tank opening. Here's a step-by-step guide on how to do it:
First, understand the capless gas tank mechanism. Capless fuel tanks have two doors in the filler neck. The outer door is easily accessible, but there is a second door behind it that can be challenging to access. This second door is designed to prevent fuel theft and reduce emissions during fuelling.
Now, let's discuss the process of using a nozzle of a similar size to the gas tank opening:
- Obtain a nozzle: Purchase or acquire a nozzle that has a similar diameter to the gas tank opening. This could be a filler nozzle or a narrow metal or plastic tube. Ford dealerships or parts centres offer nozzles specifically designed for this purpose, and they typically cost around $30.
- Disengage the locks: Insert the nozzle into the gas tank opening. The nozzle should be the same diameter as the inner door to disengage the locks or tabs on the spring-loaded door. You may need to apply some force, but be careful not to damage the mechanism.
- Use a funnel: Once you have disengaged the locks, remove the nozzle and insert a small funnel into the opening. This funnel will allow you to pour the fuel injector cleaner into the tank. You can use the funnel that came with your car, which is usually located in the trunk or storage areas.
- Add the fuel injector cleaner: With the funnel in place, carefully pour the fuel injector cleaner into the tank. Follow the instructions on the cleaner's packaging for the appropriate amount to use.
- Remove the funnel: Once you have added the cleaner, carefully remove the funnel and close the gas tank.
By following these steps, you can effectively add a fuel injector cleaner to your capless gas tank using a nozzle of a similar size. Remember to refer to your vehicle's owner's manual for specific instructions related to your car model.

Keep the funnel in a Ziplock bag to prevent odour
To add a fuel injector cleaner to a capless gas tank, you will need a funnel. This funnel should be able to open both filler neck doors, allowing you to add the fuel injector cleaner to the tank. You can refer to your car's owner's manual to understand how to use this funnel.
Now, funnels are prone to retaining the odour of the fluid they are used for, in this case, gasoline. This odour can be quite unpleasant and may linger in your car if the funnel is not stored properly. To prevent this, you can take a cue from a Chevrolet Corvette owner who keeps their funnel in a Ziplock bag in the cubby. This ensures that the funnel does not stink up or mess up the car.
It is a good idea to keep the funnel in a Ziplock bag between uses to prevent odours from escaping. The Ziplock bag acts as an effective barrier, trapping the odour inside and preventing it from spreading. This way, you can store the funnel in your car without worrying about any lingering gasoline smells.
Additionally, you can also try keeping the funnel in a well-ventilated area when not in use. This will help to dissipate any residual odours. Placing the funnel in a sealed container with an odour-absorbing agent, such as baking soda or activated charcoal, can also help to neutralise any lingering smells.
By taking these simple precautions, you can ensure that your funnel remains odour-free and ready for use when needed, without causing any unpleasant smells in your vehicle.
