If you need to temporarily patch a fuel line, it's important to know that this is a risky procedure and you should exercise extreme caution. Before you start, drain all the gas into a suitable container. If your fuel line is made of flexible plastic, get a rubber fuel line of the correct bore to match the pipe's outer diameter, cut the pipe in two, and stick a short length of the rubber hose over the cut ends, securing it with clips. If your fuel line is made of rubber, cut the pipe and stick a short piece of suitable-diameter copper or kunifer pipe in, again with clips to secure it. You can also use fabric repair tape, self-amalgamating tape, and PVC electrical insulation tape for extra strength. However, be aware that self-amalgamating tape can dissolve in petrol.

What You'll Learn
Using compression fittings to splice in a new line
Using compression fittings is a good way to splice in a new line when repairing a rotten fuel line. Compression fittings are fine for low-pressure steel lines like fuel pump lines. However, they are not recommended for high-pressure lines.
Before using compression fittings, ensure that the outside diameter of the tube is clean. If you're using brass compression fittings, be aware that they are meant to be used on copper, which is very soft. The nut pinches down on the ferrule (the brass ring) and causes it to compress the copper under it. If all goes well, it seals and you have no leak. However, if you move it after it's sealed, it will likely leak.
It is also important to note that brass compression fittings have poor resistance to vibration. The compression sleeve will lose its "tightness" on the tube, especially with a "twisting" type of vibration. Therefore, it would be safest to use carbon steel or stainless steel for alcohol fuels.
If you're looking for a temporary fix, you can use rubber patches with hose clamps. This method has been used for temporary repairs in fire sprinkler systems, where it can hold up to 200 lbs of pressure.

Replacing the bad section of hose with a garden hose
If you are looking for a quick fix to patch a fuel line, the first thing to do is to drain all of your gas into a suitable container. You can then replace the bad section of the hose with a cheap garden hose. This is not a long-term solution, and you should look to replace the fuel line as soon as possible.
To replace the bad section of the hose with a garden hose, you will need to cut out the damaged part of the fuel line. Be sure to cut out enough of the line to ensure that you are left with a clean area with minimal rust. If the end of the line is flared, the connection with the garden hose will be more secure. You can flare the end of the line yourself if you have the right tools.
Next, take your garden hose and cut it to the length required to replace the section of the fuel line you removed. You want to use as little hose as possible to make a secure connection, generally less than six inches in length. You can then attach the garden hose to the fuel line using hose clamps. Ensure that the hose clamps are fuel injection-rated and are tight enough to prevent leaks.
While this temporary fix may work for a short period, it is important to replace the entire fuel line as soon as possible. Modern rubber hoses are made of better materials and are reinforced to take the extra pressure of modern injection systems. Therefore, a proper replacement will be safer and last longer.

Using electrical tape to seal the line
While it is not recommended to use electrical tape to seal a fuel line, here is a step-by-step guide on how to do it:
First, drain all the gas into a suitable container. In this case, do not use a styrofoam cooler as it will melt when it comes into contact with gas. Once the gas is drained, poke holes in the line all around the damaged area. Next, use a lighter to warm up the line. Be cautious when using a lighter as gas and gas fumes are highly flammable. With the line warm, apply the electrical tape to the damaged area. The heat will allow the tape to melt and adhere more effectively to the fuel line.
It is important to note that this is only a temporary solution and that the fuel line should be properly replaced as soon as possible. Additionally, the electrical tape may not be effective if the fuel line is under high pressure.

Using fabric repair tape and self-amalgamating tape to seal the line
If you are looking to temporarily patch a fuel line with fabric repair tape and self-amalgamating tape, here is a step-by-step guide to help you through the process:
First, you need to assess the condition of your fuel line. If it is a braided line, it is best to change it before it bursts open. If it is a plastic, metal, or rubber line, you can attempt a repair by cutting out the damaged section and installing a new piece. Make sure you have the necessary tools and safety precautions in place before starting the repair.
For a temporary fix, you can use fabric repair tape, also known as "Atomic Tape," which has been specifically designed for fuel line repairs. This tape will help seal any small holes or leaks in the line. Clean the area around the leak and ensure it is dry. Then, wrap the fabric repair tape tightly around the fuel line, covering the leak. Overlap the tape onto the intact areas of the pipe to ensure a strong seal.
Self-amalgamating tape can also be used in conjunction with fabric repair tape for added security. This type of tape fuses to itself when activated by pressure, creating a strong, watertight seal. Wrap the self-amalgamating tape around the fabric repair tape, applying pressure as you go. Make sure there are no gaps or air bubbles between the layers of tape.
While these methods can provide a temporary solution, it is important to emphasize that they are not permanent fixes. Fuel lines operate under pressure, and even small leaks can be dangerous. Therefore, it is recommended to replace the entire fuel line or, at the very least, replace the faulty section as soon as possible. Always exercise caution when working with fuel systems and refer to a professional mechanic if you are unsure about any aspect of the repair process.

Replacing the whole line with a steel or copper alloy line
If you are looking for a more permanent solution to a leaky fuel line, you could consider replacing the whole line with a steel or copper alloy line. This option is ideal if you are looking to return your vehicle to like-new condition and prevent future leaks.
Firstly, you will need to drain all of your gas into a suitable container. This is important as you do not want to work around flammable substances. You should also be aware that gas should never come into contact with styrofoam, as it will melt.
Next, you will need to source the correct materials. Copper alloy lines are a good option as they are easy to bend and will not rust as quickly as steel. You can also use copper to replace high-pressure lines, as it can be flared or soldered to create a secure connection. If you opt for steel, be aware that it can be difficult to bend without crimping. You will also need suitable fuel line clips to secure the line in place.
When installing the new line, ensure that you follow the correct routing and mounting methods. This is important for safety reasons, and it is recommended that you do not try to re-engineer the original routing. You should also ensure that you use as little fuel injection-rated hose as possible, as this can deteriorate over time and will need to be inspected annually.
Finally, you should always refer to your local laws and vehicle inspection requirements when replacing fuel lines. For example, compression fittings are generally only suitable for low-pressure steel lines, and you may need to use flare fittings for high-pressure lines.
