What You'll Learn
Using boiling water to soften the nylon fuel line
To replace a quick connect on a nylon fuel line, you will need to soften the nylon before it can be fitted onto the fuel line. One way to do this is by using boiling water.
Nylon has a strong affinity for water due to its chemical composition, which includes an amide group. This group creates a very polar bond that attracts water molecules and is responsible for water's high boiling point. When nylon absorbs water, its glass transition temperature decreases, making it more flexible.
To use boiling water to soften the nylon fuel line, follow these steps:
- Boil a pot of water: Ensure you have a pot large enough to submerge the nylon fuel line, or at least part of it. Bring the water to a rolling boil.
- Prepare the nylon fuel line: Cut the nylon fuel line to the required length, ensuring it is slightly longer than needed to account for any shrinkage during the softening process.
- Soften the nylon: Carefully place the nylon fuel line into the boiling water. You may use tongs or heat-resistant gloves to handle the nylon, as it will be hot. Allow it to remain in the boiling water for a few minutes until it becomes pliable and flexible. The exact time will depend on the thickness of the nylon, so monitor it closely to avoid over-softening or damage.
- Remove and shape: Using tongs or heat-resistant gloves, carefully remove the softened nylon from the boiling water. Quickly but carefully shape the nylon fuel line as needed while it is still hot and pliable. You can bend it or mold it to fit the fuel line.
- Cool and fit: Allow the shaped nylon to cool down. As it cools, it will harden and retain its new shape. Once cooled, you can fit the softened and shaped nylon onto the fuel line, creating a secure connection.
It is important to exercise caution when working with boiling water to avoid burns. Additionally, while boiling water can effectively soften nylon, it is worth noting that some sources suggest using methods that do not involve heat or hot water for fuel line fittings.

Using a hair dryer to heat the nylon fuel line
When replacing the quick connect on a nylon fuel line, you may need to use a hair dryer to heat the nylon fuel line. This can be done without the use of heat or hot water, as shown in some online videos. However, if you choose to use a hair dryer, there are a few important things to keep in mind.
First, nylon is a heat-sensitive synthetic material made from plastic. While it won't shrink when exposed to heat, it can be damaged or melted by high temperatures. Therefore, it is crucial to use the lowest heat setting on your hair dryer when heating the nylon fuel line. Avoid using a tumble dryer, as it can be challenging to control the temperature accurately, increasing the risk of damaging or melting the nylon.
Before applying heat, dampen the nylon fuel line with a spray bottle filled with water. This step is essential as nylon can be damaged by direct heat application. Once the line is damp, you can carefully use the hair dryer to apply heat. Ensure that you keep the hair dryer continuously moving in a circular motion and avoid prolonged contact with any single spot.
Additionally, consider using a heat-resistant glove or similar protective gear to shield your hands from the heat. This is especially important if you are working in a confined space or need to apply heat for an extended period. Remember to exercise caution and avoid overheating the nylon fuel line, as excessive heat can lead to permanent damage or even pose a fire hazard.
By following these instructions, you can effectively use a hair dryer to heat the nylon fuel line when replacing the quick connect. Remember to work cautiously and pay close attention to the temperature to prevent any potential issues.

Using a heat gun to heat the nylon fuel line
When using a heat gun on nylon, it is crucial to maintain a lower temperature and a shorter heating time. Always use a barrier, such as a Teflon sheet, parchment paper, or a cover sheet, between the heat gun and the nylon surface to prevent burning. This barrier provides extra protection and helps distribute heat more evenly.
Additionally, it is important to be mindful of the thickness of the nylon fuel line. Thinner materials are more susceptible to burning, so it is recommended to choose a nylon line with an appropriate thickness to avoid this issue.
Practicing on an inexpensive piece of nylon before attempting any repairs is advisable. This allows you to get a feel for how the material reacts to heat and helps you perfect your technique without risking damage to the actual fuel line.
While using a heat gun on nylon can be challenging, with caution and the right technique, it is possible to successfully heat and work with this material without causing damage.
