Cut out the broken section and splice in a piece of high-pressure rubber line
If you're dealing with a leaking fuel line, one temporary fix is to cut out the broken section and splice in a piece of high-pressure rubber line. Here's a step-by-step guide on how to do this:
First, you'll need to locate the leak and assess the damage. Place a drip pan under the area to catch any fuel that drips from the line. Then, using a pipe cutter or a small hacksaw, carefully cut out the damaged section of the fuel line, ensuring that you have a straight line of at least 3 inches on either side of the cut to work with. If the leak is close to the fuel filter, you may want to consider replacing the entire line, as it may be more effective in the long run.
Once the broken section has been removed, you'll need to prepare the new piece of high-pressure rubber line. Cut it to the appropriate length, making sure it fits snugly between the two cut ends of the original fuel line. Slightly flare the ends of the original line, if possible, to create a better seal. If flaring is not an option, you can use a double hose clamp to secure the connection.
Now, it's time to splice in the new piece of rubber line. Place the ends of the original line and the new piece of rubber line together, ensuring that they are aligned properly. You can use a barbed fitting or a compression fitting to connect the two pieces. A barbed fitting is a simple solution, held in place with a small hose clamp. For a compression fitting, separate the parts, place the perforated cap on the original line, install the ferrule, and then push the line into the connector before tightening the cap.
Before you finish, test the connection by turning on your system and checking for any leaks. If you notice any leaks, tighten the connection slightly until the leak stops. Do not overtighten, as this can cause damage to the fuel line. Once you're satisfied that the connection is secure and leak-free, your temporary repair is complete. Remember, this is only a temporary solution, and you should seek a proper repair as soon as possible to ensure the long-term safety and functionality of your vehicle.

Remove the worm drive clamp, inspect the hose and metal line, and push the hose further on
To remove the worm drive clamp, you will need a flat-head screwdriver or a 1/4” hex-head nut driver. First, turn the head of the worm gear screw counter-clockwise to open the clamp. Then, slide the clamp off the hose. Once the clamp is removed, you can inspect the hose and metal line for any damage. Look for cracks, dents, or any other issues. In this case, the hose and metal line were found to be in perfect shape, with no cracks or dents, and the rubber was pliable.
After inspecting the hose and metal line, you can push the hose further onto the fitting. Ensure that the hose is fully seated onto the fitting before securing it with the clamp. To secure the hose with the worm drive clamp, first, slide the clamp onto the hose, with the worm gear screw head facing the correct direction for access to the hex-head with your screwdriver or nut driver. Then, slide the clamp back up the hose and position it over the fitting serrations or barbs. Finally, turn the head of the worm gear screw clockwise to tighten the clamp securely around the hose.
If you are having trouble accessing the worm drive clamp, there are some tools that can help, such as a hex drive socket, a piece of thin tygon tubing, or a right-angle screwdriver. Additionally, it is important to select the proper size worm gear hose clamp that matches the diameter of the hose for a tight connection.

Cut off the broken hard line inside the hose, unclamp the hard line, and slide the return hose over
To temporarily fix a leaking fuel line, you can try the following method, which involves cutting off the broken hard line inside the hose, unclamping the hard line, and sliding the return hose over:
First, make sure you have the necessary tools and safety equipment. You will need gloves and safety goggles to protect your hands and eyes from any sharp edges or fuel spillage. You will also need a pipe cutter or a hacksaw to cut through the metal line, and a wrench or a ratchet set to loosen and tighten the clamps.
Locate the leaking fuel line and identify the broken hard line inside the hose. Place the pipe cutter or hacksaw around the broken section and cut off the damaged piece of the hard line. Be careful not to cut the fuel line itself or any surrounding components. Once the broken section is removed, dispose of it safely.
Next, you will need to unclamp the hard line from the firewall. Use the wrench or ratchet set to loosen the clamp that secures the hard line in place. Set the clamp aside and gently slide the return hose over the hard line. Ensure that the hose is properly seated and secured onto the hard line.
Finally, take the clamp that you previously removed and tighten it securely around the return hose to hold it in place. Once you have finished this temporary repair, it is important to address the issue properly as soon as possible to ensure the safety of your vehicle.
This temporary fix should allow you to use your vehicle in the short term, but it is important to get a permanent repair done as soon as you can. A leaking fuel line can be dangerous and may lead to further issues if left unattended.

Remove the flared end, slide on a new fitting, and re-flare the end using a flaring tool
If you're dealing with a leaking metal fuel line connector, the easiest fix is usually to remove the flared end, slide on a new fitting, and re-flare the end using a flaring tool. This will give you a fresh new seal. Here's how to do it:
First, make sure you have the right tools for the job. You'll need a flaring tool, which is used to create a fabricated joint for joining or sealing copper tubing with a flare connection. A universal hydraulic flaring tool is a good option, as it can be used for most line flaring applications. You'll also need some tape, a saw, and a flaring die that matches the tubing's outer diameter.
Now, onto the steps:
- Unscrew any fittings and slide them up onto the steel line, using tape to hold them in place.
- Cut as close to the flare in the line as possible to remove the old flared end. Be careful not to drop any metal shavings into the fuel filter.
- Once the old flare is removed, slide a new fitting over the steel line.
- Before flaring the end of the line, make sure the new fitting is on. If you flare the line first, the fitting won't fit.
- Assemble your flaring tool according to the instructions.
- Place the tubing into the matching die set and secure it into the yoke by twisting the clamping screw.
- Close the hydraulic system inside the handle and pump to project the plunger forward.
- Open the release knob to retract the plunger and prepare for the flaring process.
- Depending on the flare shape desired, select the appropriate die. For a double flare, use the die with the imperial measurements of the tubing's outer diameter.
- Close the hydraulic handle again and pump until the lever becomes difficult to actuate.
- Turn the knob to open and retract the plunger.
- For a double flare, slot the OP 2 die into the plunger and repeat the process.
- Once the flaring is complete, retract the plunger, release the clamping screw, and extract the die set.
- Tighten the new fitting down snugly, then turn on your system and verify if there are any leaks.
- If you still see a leak, slowly tighten until the leak stops, then add a little more torque. Be careful not to wrench down too hard, as this can crack the flare and ruin your seal.
Keep in mind that this process may vary slightly depending on the specific tools and fittings you're using, so always refer to the manufacturer's instructions when in doubt.

Use fabric repair tape, self-amalgamating tape, and PVC electrical insulation tape
If you are looking for a temporary fix for a leaking fuel line, you can try using fabric repair tape, self-amalgamating tape, or PVC electrical insulation tape. These tapes can provide a quick and temporary solution to seal small leaks in the fuel line and get you back on the road.
- Prepare the Fuel Line: Before starting the repair, ensure that the fuel line is clean and dry. If possible, remove any dirt, grease, or debris from the area around the leak using a clean cloth or brush.
- Apply Fabric Repair Tape: Fabric repair tape, also known as "duck tape," can be used to cover the leak. Cut a piece of the tape large enough to completely cover the leak and stick it firmly onto the fuel line. Ensure that the tape is smooth and free of any bubbles or creases.
- Use Self-Amalgamating Tape: Self-amalgamating tape, sometimes called "Atomic Tape," is designed to bond with itself when stretched and wrapped tightly. This type of tape is ideal for repairing fuel lines as it creates a strong, waterproof seal. Stretch and wrap the self-amalgamating tape around the leak, overlapping each layer slightly, and continue wrapping until you have created a thick, secure seal.
- Secure with PVC Electrical Insulation Tape: Finally, add an extra layer of protection by wrapping PVC electrical insulation tape, or "electrical tape," around the repaired area. This type of tape is flexible, durable, and resistant to fuels and solvents. By wrapping it tightly around the self-amalgamating tape, you can further reinforce the seal and ensure that the repair holds.
While these tape solutions can provide a temporary fix, it is important to remember that they are not permanent solutions. It is always best to get a professional and permanent repair as soon as possible to ensure the safe and reliable operation of your vehicle.
