What You'll Learn
Using a screw clamp
While it is easier to use a tool designed for removing fuel lines, a screw clamp can be used in a pinch.
First, find a screw clamp and cut off the screw portion, leaving a small open-ended ring. Wrap the open-ended clamp around the fuel line, as tightly as possible, and push it into the connector. This will push apart the spring inside the connector, allowing you to disconnect the fuel line.
This method was shared by a user on an online forum, who noted that it worked well for them, but another user had some trouble with it. It is important to exercise caution when attempting this method, as using the wrong tools can damage the fuel line.
Another method for removing fuel lines without a special tool involves cutting a white BiC pen sleeve into a 1/2"-3/4" long cylinder, slicing it open, and slipping it over the line. Then, use pliers to press it into the fitting. This creates a snug fit, and the wound coil spring inside must be spread open to lift it over the male fitting end.
Other tools that can be used to remove fuel lines include a Dremel with a small cutting wheel, a thin flat-head screwdriver, side cutters, vice grips, and expanding circlip pliers.

Wrapping with plastic
While it is easier to use a tool designed for fuel line removal, there are ways to disconnect a fuel line without one. One such method is to wrap plastic around the fuel line.
To do this, first, find a piece of plastic that you can wrap around the fuel line. It should be something that can be tightly wrapped and that you can push into the fuel line connection with your fingers and a screwdriver. You could use a white BiC pen sleeve, for example. Cut the sleeve to a length of about 1/2" to 3/4", then slice it lengthwise so that it can be wrapped around the fuel line.
Wrap the plastic tightly around the fuel line. Push the plastic-wrapped section of the fuel line into the connector, using your fingers and a screwdriver. This will help to disconnect the fuel line.
It is worth noting that some people prefer using metal tools for this task, as they can be more effective at disconnecting fuel lines, especially in older vehicles. Plastic tools can be useful in a pinch, but they may not always be successful, and there is a risk of them breaking during the process.

Metal tools
While it is always recommended to use the tool designed for fuel line removal, there are some metal tools and equipment that can be used as a substitute.
One method is to use a small metal clamp, such as a screw clamp, and cut off the screw portion to create a small open-ended ring. This can then be slipped over the fuel line and pushed into the connector, releasing the tabs from the lip and disconnecting the fuel line. This method is supported by several online sources and is a quick and easy way to disconnect a fuel line without the need for a specialized tool.
Another suggestion is to use a metal line removal tool, which can be purchased online or from auto parts stores. These metal tools are preferred over plastic ones as they are stronger and less likely to break during the removal process.
It is important to note that while these metal tools can be used for fuel line removal, they may not always fit the required fuel line. It is also recommended to clean all dirt off the fuel line before attempting any removal to avoid any dirt entering the lines or tank.

Buying vs making
Fuel line disconnect tools are used to help you disconnect the fuel line from the connector without causing damage. They are inexpensive and easily available online and at local auto parts stores.
While it is possible to make your own fuel line removal tool, it is not recommended. Users who have attempted to make their own tools have reported that it took them the same amount of time to make a tool as it would have to simply purchase one. Additionally, the tool they made did not work as well as a store-bought one.
Another user who attempted to remove a fuel line without a tool ended up spraying fuel at a rate of a gallon per mile and had to be towed to a repair shop, costing them over $500. They noted that this could have been avoided if they had simply spent $15 on a tool.
If you are set on making your own tool, some users have reported success by cutting a white BiC pen sleeve into a 1/2”-3/4” long cylinder, slicing it open, and then slipping it over the line, using pliers to press it into the fitting. Another user reported success by wrapping something plastic around the fuel line, tightening it with a screwdriver, and then disconnecting the fuel line with their fingers.
However, given the low cost and ease of access to fuel line removal tools, it is generally recommended to simply purchase one to ensure the job is done correctly and safely.

Drain lines first
It is important to drain your fuel lines before removing the filter to avoid spilling half the tank. This can be done by connecting a fuel pressure gauge with a bleed-off hose to the fuel pressure test valve, and then relieving the pressure, draining the fuel into a container. The engine should not be running during this process.
Alternatively, you can pull the fuel pump fuse and start the car, which should use all the fuel in the lines. As an added measure, put the front of the car on an incline. If you are unable to find the fuel pump fuse, you can disconnect the fuel pump connector, assuming it is not too hard to reach.
If you are dealing with a generator, slightly tilt the generator so that all the fuel flows to one side and runs out of the disconnected fuel line. Once most of the fuel has drained, switch the fuel valve back to the "On" position to drain any remaining fuel.
It is also important to note that old or stale gasoline can cause problems such as starting issues, so it is crucial to drain the gas from your generator regularly to maintain its health and ensure its reliability. This should be done after an extended period of non-use, before long-term storage, or as part of routine maintenance to ensure fresh, stabilized gas in the tank.

Frequently asked questions
Some DIY options for a fuel line removal tool include cutting a white BiC pen sleeve into a cylinder, slicing it open, and slipping it over the line, or using a screw clamp by cutting off the screw part and slipping the open-ended clamp down the fuel line to the connector. You can also wrap something plastic around the hard line and push it in with your fingers and a screwdriver.
Metal fuel line removal tools are available for purchase on Amazon, eBay, and Summit. Metal tools are generally preferred over plastic ones as they are more durable.
Before removing a fuel line, ensure that the lines are drained to avoid leaks. It is also important to clean all the dirt off and to clean under the brake/fuel line guards to prevent debris buildup.
