What You'll Learn
Using a pipe cutter
To begin, secure the pipe cutter to the copper pipe. Open the jaws of the cutter using the handle, place the pipe inside, then tighten the jaws by spinning the handle. The pipe cutter will now hold the pipe in place.
Next, score the pipe. Hold the pipe with one hand, and use the other hand to rotate the handle of the pipe cutter around the pipe once or twice. You should see a faint line appear on the pipe where the blade has lightly cut into it. This line will act as a guide as you continue to cut.
Continue to rotate the handle so that the blade keeps cutting into the pipe, following the line you created. Ensure that the blade is cutting in a straight line and not spiralling down the pipe. As you cut, use the small knob on the base of the tool to tighten the cutter.
Once you have cut all the way through the pipe, you can smooth the edges with sandpaper to prepare for fittings.

Using a hacksaw blade
Cutting a copper fuel line with a hacksaw blade is a straightforward process. However, it is important to follow the correct steps to ensure a clean and precise cut. Here is a detailed guide on how to use a hacksaw blade to cut a copper fuel line:
Select the Right Hacksaw and Blade
Choose a hacksaw with a small gap between its teeth to cut cleanly through the copper pipe. Look for a hacksaw with a 32-teeth per inch (TPI) blade, as it has the shortest distance between the teeth. A 32-TPI blade is also known as a Low TPI blade. This type of blade is recommended for cutting copper pipes because it provides a precise cut.
Prepare the Copper Pipe
Before cutting, it is important to clean the copper pipe, especially if it is tarnished. Use a clean and dry cloth to wipe the pipe. You can use a vinegar and baking soda solution to effectively clean the copper surface. Once the pipe is clean, determine where you want to make the cut. Use a fine permanent marker and draw a line directly on the copper pipe to mark the cutting point. Alternatively, you can use masking tape or any other type of tape. Wrap the tape around the pipe and draw a line perpendicular to the tape.
Clamp the Copper Pipe
If possible, clamp the copper pipe to secure it in place and prevent movement. Adjust the clamp according to the pipe's size. Let the mark sit close to the clamp to ensure a stable fit. If you have a long pipe, support both ends to avoid damage caused by clamping jaws.
Cut the Copper Pipe
Hold the hacksaw with one hand and use your other hand to support the top of the saw. Place the teeth of the hacksaw directly on the mark you made. Move the blade firmly across the pipe, lifting it up as you bring the hacksaw back towards you. Continue this motion until the cut piece falls off. Avoid using a back-and-forth sawing motion to prevent blade damage and ensure a clean cut. You can also gently stroke the hacksaw backward to create a groove on the pipe before starting the full cutting motion.
Post-Cutting Steps
After cutting, clean the pipe to remove any debris. Smooth the cut edges with a reamer and sandpaper to prepare for fittings. For plumbing projects, remove any burrs or raised edges inside the pipe to prevent loud noises from water flow. You can use a round file for this purpose.

Using a multi-tool
Firstly, ensure you have the right blade for the job. Oscillating multi-tools work best with finer-toothed metal blades. These blades allow you to get close to the copper fuel line and make precise cuts. The Milwaukee M12 copper tubing cutter is a highly innovative and effective tool for this purpose.
Next, secure the copper fuel line in a clamp or vise. This will stabilise the pipe and make it easier to cut. If you're using a vise, adjust it so that the section of the pipe you want to cut extends a few inches beyond the jaws of the vise, giving you enough space to work with the multi-tool.
Now, it's time to start cutting. Position the blade of the multi-tool at the point where you want to make the cut. Ensure the blade is firmly in contact with the pipe. Turn on the multi-tool and apply gentle pressure as you slowly move the blade through the pipe. Take your time and let the tool do the work to avoid any uneven cuts.
Once you've cut through the pipe, release the pressure on the blade and turn off the multi-tool. Inspect the cut to ensure it's clean and straight. If there are any burrs or sharp edges, you can use sandpaper or a file to smooth them out.
Finally, clean the cut copper pipe to remove any metal debris or residue. You can use a 4-in-1 cleaning tool or a copper pipe cleaner for this step. This will ensure that your copper fuel line is ready for any necessary fittings or connections.
By following these steps, you can effectively cut copper fuel lines using a multi-tool, taking advantage of its precision and versatility, especially in tight or challenging spaces.

Flaring the end of the tube
Firstly, it is important to use the correct type of copper tube. When flaring Types L or K copper tube, annealed or soft temper tube should be used. It is possible to flare Types K, L or M rigid or hard temper tubes, but prior annealing of the tube end is usually necessary. The copper tube must be cut square using a tubing cutter, ensuring a straight and clean cut. After cutting, the tube must be reamed to the full inside diameter to remove any burrs or debris. This step is crucial to achieving a proper seal for the flared joint.
Next, you will need to prepare the tube end for flaring. Place a flare nut over the end of the tube, ensuring that the threads are closest to the end being flared. Select the appropriate opening in the flaring tool that matches the diameter of the tube. Insert the tube between the flaring bars of the tool. Adjust the height of the tube according to the manufacturer's instructions to achieve the desired flare length.
Now, you are ready to begin the flaring process. Position the yoke with the flaring cone over the tube end and securely clamp it in place. Turn the handle of the yoke clockwise. This action will lower the flaring cone and force the tube lip against the base of the flaring bar, creating an angled flare. Be careful not to over-tighten the cone to avoid cracking or deforming the tube. A bubble or double flare is generally recommended for a stronger and more secure joint.
Finally, inspect the flared tube end. It should have a smooth, even, and round flare that fully engages the mating surface of the flare nut without protruding into the threads. If necessary, use sandpaper to smooth out any sharp edges. A properly flared tube end will ensure a tight and leak-proof connection when joined with a corresponding flare-type fitting.
While flaring the end of the tube can be done by hand, it is important to exercise caution and follow the manufacturer's instructions for your specific flaring tool. Alternatively, you can use a tube flaring tool, which can be purchased at any automotive store.

Cleaning the cut pipe
To clean the cut pipe, you will need to remove any filings, burrs, and imperfections on the cut edge and inside each length of pipe. The best option for this job is a deburring tool, which can be cylindrical in shape with two inner cone-shaped blades, or consist of a metal or plastic handle with a small bent metal blade attached at one end. If you don't have a deburring tool, you can use a knife or the attachment on your pipe cutter.
To use the first type of deburring tool, insert the blade into the copper pipe end and scrape around the rim by hand. To remove roughness from the face of the cut rim, use a handheld rotary tool fitted with a grinding wheel accessory. For the second type of tool, simply push either of the tool's cone-shaped blades into the end of the cut copper pipe and twist the tool around by hand to remove the burrs. Alternatively, insert a grinding stone accessory on a handheld rotary tool into the pipe and let the power tool do the work of removing the interior burrs.
After deburring, you will need to clean the pipe. You can use a wire brush to clean the inside of each section of pipe and a grit or emery cloth to clean the outside. If you're cleaning a lot of pipes, you might want to invest in a wire brush that will fit on an electric drill to save time and energy.
