What You'll Learn
Using a screwdriver
Removing crimp clamps from a fuel line can be a challenging task, especially in tight spaces. One common method is to use a screwdriver to pry and twist the clamp open. Here is a step-by-step guide on how to do this:
Start by locating the crimp clamp on the fuel line. Ensure you have a suitable screwdriver that can fit into the space. Choose a small to medium-sized standard or Phillips-head screwdriver that feels comfortable in your hand. You may also use a flat-head screwdriver if it has a thin and strong tip.
Position the screwdriver at the side of the crimp "nub" or "ear." Gently insert the tip of the screwdriver into the middle of the crimp and apply slight pressure to get some leverage. Twist the screwdriver outward and downward, using the nub as a pivot point. This action will cause the crimp to "pop" open or at least loosen. Be cautious not to break or damage the fuel line itself during this process.
If the clamp is particularly stubborn, you may need to apply more force. Try grabbing the crimp with a pair of vice grips or pliers and then use the screwdriver to twist and pry it open. Alternatively, you can use the screwdriver itself to twist the top of the clamp, loosening the hose enough to slide the fuel line out. This method may require some trial and error, depending on the tightness of the clamp.
Once the clamp is loosened, carefully remove it from the fuel line. Be cautious of any sharp edges that may remain on the hose. It is recommended to replace the old clamp with a new one, such as a screw-type hose clamp, to ensure a secure connection.

Using a pair of wire/side cutters
Removing crimp clamps from a fuel line can be a challenging task, but with the right tools and techniques, it can be accomplished safely and effectively. In this case, using a pair of wire or side cutters can be a practical approach. Here's a step-by-step guide to help you through the process:
Using Wire or Side Cutters:
- Understand the Clamp Type: Before starting, it's important to identify the type of clamp you are dealing with. Fuel lines often use pinch clamps or crimp clamps, which are designed to be tightened once and cut off for removal. These clamps have a metal ring with square-shaped holes and a protruding metal ear that creates tension on the tubing when crimped.
- Prepare the Cutters: Ensure you have a suitable pair of wire cutters or side cutters that can firmly grip the clamp. Open the jaws of the cutters and position them over the metal ear of the clamp. This metal ear is the part that projects up from the ring and provides tension.
- Cut the Metal Ear: Once the cutters are in position, squeeze the handles firmly together to snip off the metal ear. This step may require some force, depending on the thickness of the metal. Make sure you are wearing appropriate safety gear, including gloves and eye protection, to catch any sharp fragments.
- Remove the Clamp: After cutting the metal ear, the tension holding the clamp in place should be released. Gently pull the ring of the clamp off the hose. If needed, use a screwdriver or similar tool to carefully pry the clamp open and slide it off without damaging the fuel line.
- Clean the Area: Before installing a new clamp, it's essential to clean the area thoroughly. Remove any debris or remnants of the old clamp to ensure a secure and leak-proof connection. You can use a wire brush or a clean cloth to wipe the area and prepare it for the new clamp.
- Install a New Clamp: Finally, install a new clamp according to the manufacturer's instructions. You can use a screw-type hose clamp or a similar reusable option. Ensure the new clamp is securely tightened to prevent leaks.
Using wire or side cutters to remove crimp clamps from a fuel line requires precision and caution. Always exercise safety measures to protect yourself and the surrounding components. If you're unsure or working with delicate materials, consider seeking professional assistance to avoid any potential damage.

Using vice grips
Removing crimp clamps from a fuel line can be a challenging task, and it is important to exercise caution to avoid damage or injury. One method that can be used is vice grips. Here is a step-by-step guide on how to use vice grips to remove crimp clamps from a fuel line:
First, it is important to assess the condition of the fuel hose. If the hose is old, it may have become hard and brittle, increasing the risk of damage when using vice grips. Consider using a different tool if the hose is in poor condition, as vice grips can be harsh on old fuel hoses.
Next, prepare the vice grips by adding a layer of protection between the jaws and the fuel line. This can be done by wrapping the jaws with several layers of American cardboard, as suggested by one user. This will help to distribute the clamping force more gently and reduce the risk of damaging the fuel hose.
Now, carefully clamp the vice grips onto the tab of the crimp clamp. Ensure that the grips are securely in place and will not slip. Once the vice grips are clamped onto the tab, you can begin to apply force. Twist the vice grips, using them to leverage and break the crimp clamp. This should be done with caution and controlled force to avoid any sudden breaks that could cause injury.
After breaking the crimp clamp, you may need to unwind it from the fuel line. Use a screwdriver or similar tool to carefully twist and pop open the clamp, being careful not to break anything. Finally, slide the broken clamp off the fuel line. It is recommended to replace the fuel line with a new one after removing the old clamp.

Using a dremel or angle grinder
However, if you choose to use a Dremel or angle grinder, proceed with caution. First, ensure that the area is well-ventilated and that there are no sources of ignition nearby. Wear appropriate safety gear, including eye protection, a respirator, and gloves.
Next, locate the crimp clamps on the fuel line. If the area is difficult to access, you may need to use a smaller Dremel or angle grinder to reach the clamps. Position the tool carefully so that you can cut through the clamps effectively.
Start by cutting sideways through the edge of the material, being careful not to damage the surrounding components. You may need to apply consistent pressure to cut through the stainless steel clamps effectively. Once you have cut through the clamps, they should be loose enough to slide off the fuel line.
After removing the clamps, it is important to replace them with new ones. You can use screw-type hose clamps as a safer alternative to crimp clamps.
