Replacing a metal fuel line with a rubber one is possible, but it may not be a good idea. While some people have used rubber fuel lines successfully, others have found that the rubber collapsed and cut off fuel flow. It is also difficult to attach a rubber line to the two ends of a metal line, and some people have had to use hose clamps, which they don't trust.

What You'll Learn
The rubber fuel line can collapse and cut off fuel flow
It is possible to replace a metal fuel line with a rubber one, but there are some issues to be aware of. The rubber fuel line can collapse and cut off fuel flow, as one user found out when they tried to replace a 5-6 inch section of metal fuel line with rubber. They recommend using the shortest piece of rubber fuel line possible as a temporary fix until a replacement metal line can be found. Another user had a similar experience, finding that the rubber line collapsed and cut off fuel flow after only a few months. They suggest using high-pressure fuel line to avoid this problem.
One of the main challenges when replacing a metal fuel line with a rubber one is getting the rubber line to hold on to the two ends of the metal line. If you cut out a section of the metal line, you will be left with two bare ends of metal with no ribs to hold the rubber line in place. Regular hose clamps can be used, but some users don't trust them. One solution is to have a shop weld on some ribs and then use two clamps to hold the rubber line in place.
Another consideration when replacing a metal fuel line with a rubber one is the 90-degree bend that will be created. This can be restrictive and may require the use of a tube bender to get the desired shape.
Overall, while it is possible to replace a metal fuel line with a rubber one, there are some potential issues to be aware of, including the risk of the rubber line collapsing and cutting off fuel flow. It is recommended to use the shortest piece of rubber fuel line possible as a temporary fix until a replacement metal line can be found.

The rubber hose can be used as a temporary fix
Yes, a metal fuel line can be replaced with a rubber hose, but this is only recommended as a temporary fix. The rubber hose can collapse and cut off fuel flow, so it is not a long-term solution. If you do use a rubber hose, make sure it is a high-pressure fuel line and use the shortest piece you can. You will also need to use hose clamps to attach the rubber hose to the metal line, but be aware that these may not be secure enough.

The rubber line can be restrictive
In addition, if you use a long piece of rubber fuel line, it may collapse and cut off fuel flow. Therefore, it is recommended to use the shortest piece of rubber fuel line you can get away with. This would only be a temporary fix until a replacement metal line is found.

The rubber line may not hold on to the two ends of the metal line
If you are going to replace a metal fuel line with a rubber one, it is recommended that you use the shortest piece of rubber fuel line that you can. This is because, if the rubber line is too long, it may collapse and cut off the fuel flow. One user reported that a 5-6 inch section of rubber collapsed and cut off the fuel flow.
Another user reported that they ran a rubber fuel line on their engine for a year and it was fine. They used a rubber line from the pump to a filter, and then another rubber line to the carb.
If you are going to replace a metal fuel line with a rubber one, you will also need to consider the bend of the rubber line. The 90-degree bend of a rubber fuel hose can be restrictive.

The rubber line can be held on with hose clamps
Yes, a metal fuel line can be replaced with rubber, but it is recommended that you use the shortest piece of rubber fuel line possible. One user reported that they tried this with a 5-6 inch section of rubber and the rubber collapsed and cut off fuel flow. Another user said that they ran a rubber fuel line on their engine for a year and it was fine.
If you do decide to replace a metal fuel line with rubber, you will need to use hose clamps to hold the rubber line in place. One user said that they had to fix the same problem on their underbody lines by welding some ribs and using two clamps.
