Cutting a braided fuel line can be a tricky task, but with the right tools and precautions, it can be done efficiently and safely. It is important to use specific tools such as braided stainless steel hose cutters with long handles and a rubber grip, a hand grinder with a cut-off wheel, or an air-powered die grinder to ensure a clean cut without any fraying. To prevent the steel braiding from getting messed up, one can also wrap the cutting area with electrical or duct tape before cutting in the middle of the tape. Additionally, stabilizing the hose with a vise and wearing protective gear like gloves and glasses are crucial safety measures.

What You'll Learn
Use a hand grinder with a cut-off wheel
To cut a braided fuel line using a hand grinder with a cut-off wheel, you should first wrap the area you are going to cut with electrical tape. It is recommended to wrap the area 3-4 times, with some sources suggesting that duct tape can also be used, and that you should wrap the area with tape 3 times with duct tape, and once or twice with electrical tape. Once the braided fuel line is wrapped, you should then cut through the tape and the line with the cut-off wheel attached to your hand grinder. It is recommended to go slowly and in a straight line, and to wear protective clothing, such as glasses, and to use the grinder guard. After cutting, you can then fit the braided fuel line into the fitting, which may require a layer or two of tape to be removed.
It is also possible to use a die grinder with an abrasive cut-off wheel to cut through a braided fuel line. To do this, you should wrap the hose with black tape to stabilise the wires, and then cut through the tape and the hose with the die grinder and cut-off wheel. This method is reported to leave no frayed ends and allows you to put the hose ends on in seconds.
If you are using a hand grinder with a cut-off wheel, it is also recommended to clamp the braided fuel line down in a vice to keep it steady while you cut.
It is important to note that, if you are using a cut-off wheel, you should ensure that the braided fuel line does not fray, as this will cause issues when trying to fit the line into the fitting.

Wrap the line with tape to prevent fraying
Wrapping the line with tape is an important step to prevent fraying when cutting a braided fuel line. This is a crucial step as any fraying can cause issues when fitting the line. The tape should be wrapped tightly around the braided line, with some sources recommending electrical tape and others duct tape. It is important to wrap the tape around the line multiple times to ensure it is secure. One source recommends wrapping electrical tape around the line three to four times, while another suggests wrapping duct tape around the line once or twice.
When wrapping the tape, it is important to ensure that the line is stable and securely mounted. This can be achieved by clamping the line in a vise, which will also help during the cutting process. The tape will provide a stable surface to cut, preventing the blade from catching on the braided material and causing fraying. It will also help to protect the line from the blade, ensuring a clean cut.
After wrapping the tape, the cutting can begin. It is important to use a sharp blade or a cutting tool specifically designed for cutting braided lines, such as braided hose cutters or an air-powered die grinder with a cutoff wheel. The tape should remain on the line during the cutting process and cut through the middle of the tape. This will help to ensure that the blade does not come into direct contact with the braided material, reducing the risk of fraying.
Once the cutting is complete, the tape can be removed, and the fitting can be installed. However, some sources suggest leaving the tape on when putting on the fitting. If the tape is removed, it is important to ensure that there is no fraying. Any fraying can cause issues with the fitting and may require starting the process again with a new piece of the line.

Use a set of hose cutters
Using a set of hose cutters is one of the best ways to cut a braided fuel line. Hose cutters are designed specifically for cutting braided stainless steel hoses and can make quick work of cutting the hoses to the desired length. They are also known as braided stainless hose cutters or cable cutters.
Before using the hose cutters, it is important to prepare the fuel line to prevent fraying. Wrap a couple of inches of the hose tightly with electrical tape, duct tape, or masking tape. This will help keep the braid from fraying during the cutting process and provide a clean place to mark your cut. Make sure the tape is wrapped securely, with some sources recommending two to four revolutions around the hose.
When using the hose cutters, follow the manufacturer's instructions for safe and proper use. Hose cutters typically feature long handles for better leverage and a rubber no-slip grip to ensure a comfortable and controlled cutting action. Position the cutters at the desired cutting point, marked on the tape, and apply pressure to the handles to cut through the braided fuel line.
After cutting the fuel line, carefully remove the tape. It is important to note that removing the tape too early can cause the braid to loosen and fray. Some sources recommend leaving the tape on until you are ready to assemble the hose and apply the fitting. Once the tape is removed, you may need to blow out any residue or debris inside the hose using clean, dry air or a compressor.

Put the fitting on at an angle
When putting the fitting on a braided fuel line, it is important to start by placing it on the hose at an angle. This is a crucial step to ensure that none of the braided steel gets caught or tangled during the installation process. By inserting the fitting at an angle, you can smoothly guide it onto the hose without any snags.
To begin, hold the fitting at a slight angle to the end of the hose. You want to create a small gap between the fitting and the hose, which will allow for easier insertion. Gently squeeze the end of the hose to slightly reduce its diameter and create a tapered shape. This minor adjustment will make it simpler to slide the hose into the fitting without forcing or catching any of the braided steel wires.
As you insert the hose into the fitting, pay close attention to the braided steel. Ensure that none of the wires are catching or getting trapped during this process. Use a gentle back-and-forth motion if needed to guide the hose into the fitting smoothly. Once the hose is fully inserted, you can proceed to the next step of securing the connection.
It is worth noting that preparing the hose end before inserting the fitting can also help prevent tangling issues. Wrapping the end of the hose with electrical tape or duct tape a few times can provide a smoother surface for insertion. Just remember to remove a layer or two of tape after cutting to ensure a proper fit. Taking these precautions will help you avoid the frustration of dealing with tangled or frayed braided steel during the installation of the fitting.

Use a die grinder with an abrasive cut-off wheel
Using a die grinder with an abrasive cut-off wheel is an effective way to cut a braided fuel line. This method can be done with a hand grinder or an air-powered die grinder. To start, wrap the braided fuel line with electrical tape or duct tape to stabilize the wires and prevent fraying. It is recommended to wrap the tape around the hose three to four times, with some suggesting wrapping it tightly and cutting in the middle of the tape.
When using the die grinder, it is important to go slow and straight. For safety, be sure to wear protective gear, such as gloves and safety glasses, and use the grinder guard. Additionally, clamping the braided fuel line in a vise can provide more stability during the cutting process. After cutting, you may need to unwrap a layer or two of the tape to fit the braided fuel line into the fitting.
It is worth noting that some people prefer to use a light oil to lubricate the fitting before wrapping the tape. This can make the process of inserting the fitting easier. However, others suggest leaving the tape on during this step. It is crucial to ensure that there is no fraying on the cut braided fuel line, as it can cause issues when fitting.
Using a die grinder with an abrasive cut-off wheel is a popular method for cutting braided fuel lines, and with the right tools and precautions, it can be done efficiently and safely.
