The best way to repair a rusty fuel line is to replace the entire steel line
Although it is possible to replace a rusty fuel line with a rubber hose, the best way to repair a rusty fuel line is to replace the entire steel line. Rubber hoses can be used to replace rusty fuel lines, but they are not ideal as they will seep fuel if the outside of the steel line is rusty or has a rough, uneven surface. If you do decide to use a rubber hose, it is recommended to use the more expensive fuel injection clamps and to flare the end of the hose to ensure a more secure connection.
To replace a rusty fuel line with a rubber hose, you will need to cut the rusted line out and replace it with a rubber hose and hose clamps. It is important to use protective sleeves for heat and rubbing and to ensure that the hose is not too tight.
When replacing a rusty fuel line, it is best to use as much steel as possible and as little rubber hose as necessary. This is because steel is a more durable material than rubber and is less likely to leak or fail over time.
If you are unable to replace the entire steel line, you can try to repair the rusty area by sanding or grinding down the rust and then painting or coating the area to prevent further rusting. However, this may only be a temporary solution, and it is best to replace the entire line if possible.

If you use a rubber hose, make sure to use the more expensive fuel injection clamps
If you're replacing rusty old fuel lines with rubber hose, it's important to use the more expensive fuel injection clamps. This is because rubber hose will seep fuel if the outside of the steel line is rusty or has a rough, uneven surface. The more expensive fuel injection clamps will create a more secure connection between the rubber hose and the steel line, reducing the risk of fuel leaks.
When replacing a rusty fuel line with a rubber hose, it's important to use as much steel as possible and as little rubber hose as possible. This will help to reduce the risk of fuel leaks. Find a clean area on the steel line with minimal rust and flare the end if possible. This will create a more secure connection with the rubber hose.
It's also important to use protective sleeves when installing the rubber hose to protect against heat and rubbing. This will help to ensure the safety and longevity of the repair.
Finally, be careful not to overtighten the hose clamps. This can cause damage to the rubber hose and reduce its effectiveness.

By using protective sleeves and the correct clamps, you can help to ensure that your rubber hose fuel line is secure and protected from heat and rubbing, which could cause damage or leaks. It's also important to note that rubber hose should only be used as a last resort, and it's always best to replace the entire steel line if possible.
In addition to using protective sleeves, it's also important to choose the right type of rubber hose for your application.
