Flaring a fuel line for a push-in connector is a process that involves creating a flare at the end of a tube to facilitate a secure connection. This technique is commonly used in automotive applications, such as fuel lines and radiator trans coolers, and requires specific tools like flaring kits and dies. The flare allows for a tight and safe join between the fuel line and the connector, ensuring a smooth flow of fuel without leaks. The process of flaring can vary depending on the vehicle and the specific connector design, with some connectors requiring a more gentle flare to prevent damage to the fuel hose.

What You'll Learn
Using a double flare kit
To begin the process, you will need to cut the fuel line to the desired length using a tubing cutter. This ensures a clean cut that is free of filings or debris, which could potentially damage sensitive fuel system components. It is important to have the correct length before starting the flaring process.
Once the fuel line is cut to length, you can begin using the double flare kit. The kit will come with specific instructions, but the general process involves clamping the line securely in a vice and using a flaring tool to create the double flare. This two-step process involves first creating the initial flare and then using the flaring tool to shape the flare to the desired angle and thickness.
It is important to note that creating a double flare requires some practice to perfect the technique. It is also crucial to ensure that the fuel line is securely clamped and that you are wearing appropriate safety gear, including eye protection, during the flaring process.
By following these steps and using a double flare kit, you can effectively flare a fuel line for a push-in connector, ensuring a secure and leak-free connection.

Using a Mastercool flaring set
Flaring a fuel line for a push-in connector requires a flaring tool set. Mastercool offers a range of flaring tool kits that can be used for this purpose. Here is a step-by-step guide on how to flare a fuel line using a Mastercool flaring set:
Choose the Right Mastercool Flaring Kit:
Mastercool offers different flaring tool kits, such as the 72485-PRC Universal Hydraulic Flaring Tool Set and the 72400 GM Fuel Line Flaring Kit. The 72485-PRC set is a universal kit that can fabricate flares for various applications, including GM fuel lines, brake lines, and transmission lines. The 72400 kit, on the other hand, is specifically designed for fabricating the flares found on most GM fuel lines and some GM truck power steering pump return lines. Choose the kit that best suits your specific application.
Prepare the Fuel Line:
Before flaring, ensure that the fuel line is properly cut to the correct length and deburred to remove any sharp edges. It is important to work with a clean fuel line, so consider cleaning the tube with a suitable solvent to remove any dirt, grease, or oil.
Select the Appropriate Die and Adapter:
Mastercool flaring sets come with different dies and adapters. Select the appropriate die and adapter for your specific application. For example, the 72485-PRC set includes Push Connect Adapters in various sizes (1/4", 5/16", and 3/8"), as well as corresponding Die Sets. Refer to the kit's instructions to identify the correct die and adapter for your fuel line size.
Insert the Fuel Line into the Flaring Tool:
Following the kit's instructions, insert the fuel line into the flaring tool. Ensure that the fuel line is securely held in place by the clamping mechanism.
Apply Pressure to Create the Flare:
Activate the flaring tool according to the instructions. This typically involves applying pressure using the hydraulic ram or pump assembly to create the flare on the end of the fuel line. The flaring tool will shape the end of the tube to form the desired flare.
Inspect the Flared Fuel Line:
Once the flaring process is complete, release the fuel line from the flaring tool and inspect the flare. Ensure that the flare meets the required specifications and is free of defects or imperfections.
By following these steps and using a Mastercool flaring set, you can flare a fuel line to accommodate a push-in connector. Mastercool's flaring tools are trusted by professionals and designed to deliver precision flares, making the process more accessible and efficient for automotive repairs and modifications.

Using a crimping ring
Flaring a fuel line is essential to ensure a tight connection between the steel or copper line and the fittings. Here's a detailed guide on using a crimping ring to flare a fuel line for a push-in connector:
- Select the Appropriate Crimping Ring Size: Choose a crimping ring that matches the size of your fuel line. For example, an 8mm crimping ring is suitable for creating a tight connection on a steel line.
- Secure the Crimping Ring: Tightly secure the crimping ring to the steel fuel line. This step is crucial to ensure a strong and leak-proof connection.
- Adjust the Fuel Line Length: If needed, you can shorten the fuel line between the crimping ring and the end to position the flare closer to the end of the line.
- Create the Flare: Crimp the crimping ring tightly onto the steel line to form a bulb-like shape. This bulb will slide over the fuel hose, creating a secure connection.
- Tighten with a Nut: Use a nut to tighten the crimping ring further onto the fuel line. This ensures that the connection is secure and reduces the risk of leaks.
- Cut the Nut for Subsequent Flares: If you need to create a second flare on the same fuel line, you will need to cut open the nut to remove it from the line before proceeding.
- Secure the Fuel Hose: Finally, slide the fuel hose over the flared end of the fuel line and secure it with a hose clamp. This will create a tight and safe connection, preventing fuel leaks.

Using a S.U.R.&R kit
Flaring a fuel line for a push-in connector can be done using a S.U.R.&R kit, which is a leading supplier of fluid line repair kits and specialty tools. The company started by repairing damaged fuel sending units and later developed products for fuel system repair and replacement.
The S.U.R.&R kit is an effective way to flare a fuel line, as it comes with metal ends and the rest is made of poly line. This makes it easy to work with and is also cost-effective. The kit includes the necessary tools to flare the fuel line, such as a flaring tool, and the push-on fuel line connectors are made from high-quality brass, making installation easy and providing a leak-free seal.
To use the S.U.R.&R kit, start by measuring and cutting the fuel line to the appropriate length. Then, following the instructions provided with the kit, use the flaring tool to create the flare on one side of the tube. The flare should be wider and set farther back from the end of the tube, as this is the design used by GM for their "push to connect" fuel line flares.
Once the flare has been created, the push-on fuel line connector can be installed. The connector joins two lengths of nylon fuel line together, providing a painless and leak-free seal. It is important to ensure that the connector is securely in place before continuing with the fuel line installation. With the S.U.R.&R kit, you can be assured of a high-quality and innovative solution for your fuel line repair or replacement.

Using a single flare die
Once assembled, the tool is ready to use. Depending on the flare shape desired, the die will be different: a double flare will use a die labelled with the imperial measurements of the tubing's outer diameter, while other dies will be labelled with details such as ISO, CONNECT, and GM FUEL. The dimensions and purpose of each die are labelled in the box and embossed into the side of the die. Once the new die is loaded, the hydraulic handle can be closed and pumped. From there, the knob can be turned to open, retracting the plunger.
It's important to note that for double flares, there will also be an OP 2 die that must be slotted into the plunger, and the process repeated. Once the flare-forming process is completed, the plunger can be retracted, the clamping screw released, and the die set extracted. While the Universal Hydraulic Flaring Tool is a complex tool, it is a useful piece of equipment that cuts down on flaring time by having multiple functions in one toolkit.
