If you're looking to plug a broken fuel line, there are a few different methods you can try. You could use compression fittings, which are suitable for low-pressure steel lines, or flare the line with new fittings and unions. Alternatively, you could replace the damaged section of hose with a cheap garden hose or use duct tape and rubber bands to seal the leak. If you're looking for a more permanent solution, you can drill out the fuel line and insert copper tubing, using epoxy to seal the crack.

What You'll Learn
Using compression fittings
Compression fittings are a good option for plugging a broken fuel line. They can hold hundreds of psi, so they are suitable for fuel pump lines. You can use compression fittings without flaring if you are only splicing in a line.
To use compression fittings, you will need to splice the line. This involves cutting the fuel line and inserting a new section of tubing. You can use tubing with a smaller outside diameter, such as 1/4" OD tubing, to fit inside the existing fuel line. This may require drilling out the fuel line to create a larger opening.
It is important to note that compression fittings may not be suitable for high-pressure fuel lines. The suitability of compression fittings may also depend on your location and vehicle inspection requirements.
After splicing the line with compression fittings, it is recommended to cover the repaired area with a layer of epoxy to ensure a secure seal. You can use masking tape to prevent epoxy from getting on the connecting parts of the tubing.

Flaring the line with new fittings and unions
If you're splicing the line, you can either use compression fittings or flare the line with new fittings and unions.
It's important to note that flaring the line with new fittings and unions may not be suitable for all types of fuel lines. In particular, it may not be recommended for high-pressure fuel lines. It's always important to consult a professional or a qualified mechanic before attempting any repairs on your vehicle's fuel system.

Replacing the bad section of hose with a garden hose
You can replace the bad section of hose with a garden hose, but this is not recommended as it is a fire hazard.
Firstly, drain all of your gas into a suitable container. You can use a styrofoam cooler, but be aware that styrofoam melts when it comes into contact with gas.
Next, cut the hose to the length you need and insert it into the fuel line. You may need to drill out the fuel line to get the hose to fit inside. If you don't want to drill, you can use smaller tubing.
Once the hose is in place, cover the entire area in a thick layer of epoxy. Allow the epoxy to dry and then wrap the tubing in masking tape about an inch past the crack. This will prevent the epoxy from getting on the part of the tubing that needs to connect to the fuel line.
Alternatively, you can use compression fittings to splice the line. This method is fine for low-pressure steel lines like fuel pump lines.

Using duct tape and rubber bands
Duct tape and rubber bands can be used to plug a broken fuel line. The leaking fuel will fuse the tape and rubber bands together, making the seal airtight.

Covering the area with a thick layer of epoxy
To plug a broken fuel line, you can use a quick-setting plastic bonding epoxy. Covering the area with a thick layer of epoxy will ensure that there are no leaks.
Before applying the epoxy, you should drain all of your gas into a suitable container, such as a styrofoam cooler. You can then replace the bad section of hose with a section of cheap garden hose. Alternatively, you can use duct tape and rubber bands to seal the leak.
To apply the epoxy, start by wrapping masking tape around the part of the tubing about an inch past the crack. This will prevent you from accidentally getting epoxy on the part of the tubing that needs to connect to the quick-disconnect fuel line. Put on rubber gloves to protect your fingers from the quick-setting epoxy. Then, apply a thick layer of epoxy to the entire area, making sure to cover the crack completely.
Once the epoxy is dry, check for any leaks. If there are no leaks, you can remove the masking tape. Your fuel line should now be securely sealed and ready to use.
