What You'll Learn
Disconnecting plastic fuel line fittings
For newer GM cars, there is often a redundant clip in place that must be removed before disconnecting the fuel line. This can be done by simply pulling up on the clip tab, releasing it from the fuel line. This clip is an important safety feature, ensuring that the fuel line is fully engaged when reattached.
To successfully disconnect the plastic fuel line fittings, a collection of small plastic release tools is required. These can be purchased as a kit, such as the Lisle angled QD fuel-line kit (PN 39400), or individually at a low cost. In some cases, a special tool designed specifically for GM fuel line disconnection may be needed. It is important to use the correct tools to avoid damage to the fittings and fuel lines.
In some cases, warming the hose end with a heat gun can make it easier to remove the fuel line. This method requires practice to ensure that heat is applied slowly and evenly to avoid damaging the outer shell of the hose. Additionally, some people recommend using a razor blade to carefully separate the fuel line from the fitting. However, it is important to note that cutting the fuel line may not be the best option if you plan to reuse it.
When dealing with fuel lines, it is crucial to prioritize safety. GM factory fuel systems operate at high pressures, and even a small leak can quickly become dangerous. Always take your time, use quality products, and pay attention to detail during the disconnection process.

Using a special tool to pop the feed
Compressed air can be used to blow out any dirt in the fitting before attempting to disconnect the fuel line. A light lubricant, such as WD-40, can also be sprayed into the fitting to aid in the process. When inserting the tool, it is important to press the fitting toward the tool while using a twisting motion before attempting to pull it apart.
If the fitting is plastic, the tool may not be necessary. Instead, one can simply push or release the lock(s) to disconnect the line. However, this is not as easy as it sounds, and it may be worth purchasing the fuel line disconnect tool to make the job easier.
In some cases, the outside diameter of the tool may be too small to release the connector's clips. In this case, a shim can be used to increase the diameter of the tool. For example, one can shim the tool's opposite side with layers of a matchbook cover, holding the working side of the tool open a bit wider. Once the shimmed tool is pushed into the connector, it should pop right off.

Disconnecting without a tool
Disconnecting GM fuel line connectors without a tool can be challenging, but it is possible. Here are some methods that have been suggested by people who have faced similar issues:
One method is to use screwdrivers to push the tabs up and then pull out the line. It is important to depressurize the fuel system first. This method may take some time and adjustments to get the screwdrivers positioned just right to make the connector come off.
Another approach is to use a zip tie. Take a short piece of zip tie and curl it as you stuff it into the spring-type connector. This will push apart the spring inside and release the connector.
If you have a screw clamp, you can try cutting off the screw portion to create a small open-ended ring. Slip this ring down the fuel line to the connector and push it in, which will also push apart the spring and release the connector.
For plastic connectors, you may not need any tools at all. Simply pushing or releasing the lock(s) can sometimes be enough to separate the lines.
Finally, some people have reported success by wrapping something plastic or metal around the fuel line and pushing it in to release the connector. This could be a creative solution if you have some flexible material that can fit tightly around the line.
Remember that these methods may not work for all types of GM fuel line connectors, and it is always important to exercise caution when working with fuel lines to avoid any potential hazards.

Disconnecting with a cheap tool set
Disconnecting GM fuel line connectors with a cheap tool set is possible, but it may be more challenging and time-consuming than using the correct tool. Here are some methods that have been suggested by people who have faced the same challenge:
Using Screwdrivers: Some people have reported success in using screwdrivers to disconnect GM fuel lines. This method involves depressing the tabs with the screwdrivers to release the line. However, it is important to depressurize the fuel system first to avoid any safety hazards. This method may take some time and patience to get the screwdrivers positioned correctly.
Snipping and Wrapping: Another method involves snipping off the screw portion of the clamp and tightly wrapping the remaining piece around the fuel line. This wrapped piece can then be pushed into the connector using fingers and a screwdriver to release the line.
Using Plastic Tools: Some people have suggested using plastic tools or materials to disconnect the fuel line. These can include plastic disconnect tools or wrapping something plastic around the hard line and pushing it into the connector. However, it is important to note that plastic tools can break easily, especially when dealing with older, rusty vehicles.
Compressed Air and Lubricant: Before attempting to disconnect the fuel line, it is recommended to use compressed air to blow out any embedded dirt in the fittings. Additionally, spraying a light lubricant, such as WD-40, into the fitting can help. Twisting the fuel line to free up the O-rings may also be beneficial.
It is important to note that while these methods may work, investing in the correct fuel line disconnect tool, such as the OTC 6509, can save time and frustration. This tool is designed to fit into tight spaces and accommodate different fuel line sizes, making it a versatile option for GM vehicles.

Disconnecting with rust buildup
Disconnecting GM fuel line connectors with rust buildup can be challenging and may require some special tools. Here are some detailed instructions to guide you through the process:
First, identify the type of connector you are dealing with. GM fuel line connectors typically have either a squeeze-type release or a push-on mechanism. The former usually has plastic ears or tabs that need to be compressed to release the connector, while the latter may require more force to disconnect.
If you are dealing with a squeeze-type release connector, try using your fingers or a pair of pliers to compress the plastic ears or tabs. In some cases, rust buildup may prevent the connector from being squeezed adequately. If this is the case, you may need to use a specialized tool, such as the Lisle fuel quick disconnect tool or a similar alternative. These tools are designed to be inserted into the connector and can provide more force than manual squeezing. However, be cautious when using metal tools, as they can damage the plastic components if excessive force is applied.
For push-on connectors, you may need to cut and splice the fuel lines. This process will require a fuel line forming kit, which can be purchased from auto parts stores or online. When cutting the fuel lines, ensure you have adequate protective gear, including eye protection and gloves, and be cautious of any fuel spillage. Once the lines are cut, you can install new connectors or repair the existing ones by cleaning and removing any rust buildup before reinstalling them.
Rust buildup can also be prevented in the future by regularly riding your vehicle, ensuring a continuous flow of fuel through the system. Additionally, consider using fuel stabilizer, a chemical additive that strengthens the bond of fuel molecules, reducing the likelihood of rust formation.
