Clear tubing can be used for fuel lines, but it is not recommended unless it is specially made for this purpose. While clear tubing is suitable for chemicals, gases, and greases, it may not be able to withstand gasoline or other hydrocarbons. Clear vinyl tubing, for example, will harden and crack over time when exposed to gasoline or ethanol. Clear PVC tubing is also not suitable for fuel lines, as ethanol will slowly eat away at it, causing leaks. For clear fuel lines, Tygon tubing is recommended, but it is expensive and requires additional clamps to keep it in place.

Clear vinyl tubes are suitable for chemicals, gases, and greases but not gasoline unless specified
Clear vinyl tubes are versatile and can be used for a variety of applications, but there are important considerations when it comes to their suitability for chemicals, gases, greases, and gasoline.
Firstly, it is important to understand that clear vinyl tubes are not a homogeneous group, and there are many variants, each with unique performance characteristics. While they are generally suitable for chemicals, gases, and greases, their compatibility with gasoline is a more complex issue.
The key factor in determining the suitability of a clear vinyl tube for gasoline is its rating. If a clear vinyl tube is specifically rated for gasoline, it can be used for that purpose. However, ordinary vinyl tubing that is not rated for gasoline should be avoided due to safety concerns. The risk of fire is a critical factor to consider when choosing tubing for gasoline.
To identify if a clear vinyl tube is suitable for gasoline, look for specific information on the product. This could include a maker's name, a product number, or any indication that it is designed for use with petroleum products. Additionally, cross-linked polymer tubing is more suitable for fuel applications. Polyvinyl alcohol is an example of a non-cross-linked material that is fuel-resistant, but it has the drawback of dissolving in water.
When using clear vinyl tubing for gasoline, regular maintenance is important. It is recommended to replace the tubing approximately every year to ensure optimal performance and safety. This is especially relevant considering that clear vinyl tubing can harden, crack, or discolour over time, which may affect its performance and integrity.

Tygon tubing is a good option for clear fuel lines but it is expensive
When it comes to fuel lines, clear tubing has its advantages. It allows for visual flow monitoring, which can be useful for troubleshooting and maintenance. While there are various options for clear tubing, Tygon tubing stands out for its durability and compatibility with different fuels and applications.
Tygon tubing is a type of thermoplastic elastomer tubing that is highly resistant to fuels and industrial lubricants. It is designed to resist swelling, hardening, and cracking caused by hydrocarbon-based fluids, making it a long-lasting solution for fuel lines. The tubing is also flexible, easy to install, and tight-fitting, ensuring a secure connection.
One specific type of Tygon tubing, the Tygon F-4040-A, is a popular choice for fuel lines. It is made of high-quality Orm-style hose material and is suitable for various applications, including oil injection on watercraft and fuel feed on 2-stroke yard equipment. This type of tubing is known for its flexibility and sturdy construction, making it a preferred option for many users.
However, one of the main drawbacks of Tygon tubing is its cost. Some users have mentioned that it is more expensive than other types of tubing, such as PVC. Despite its higher price, Tygon tubing is known for its quality and performance, with users reporting that it is well-made, flexible, and sturdy. For those seeking a reliable and durable solution for their fuel lines, Tygon tubing is a good option, despite its higher price point.

McMaster-Carr carries industrial tubing suitable for fuel lines
Clear tubing can be used for fuel lines, but it is important to ensure that the tubing is specifically rated for gasoline. While vinyl tubes can be used for chemicals, gases, and greases, their suitability for gasoline is unclear. Some clear tubing options may harden, crack, or discolour over time, so regular maintenance and replacement may be required.
One specific product offered by McMaster-Carr is the Type 304 Stainless Steel Welded Tubing. This tubing is available in a lot of two, with a wall thickness of 0.028 inches and a length of 3 feet each. Stainless steel tubing is known for its durability and corrosion resistance, making it suitable for fuel line applications.
Additionally, McMaster-Carr likely carries other tubing materials suitable for fuel lines, such as reinforced vinyl or urethane tubing. These materials offer different benefits, such as urethane tubing's ability to remain soft over time, providing flexibility in fuel line applications.
When choosing a clear tubing for fuel lines, it is essential to consider factors such as temperature ratings and compatibility with the specific fuel or oil being used. Ensuring that the tubing can withstand the heat and chemical properties of the application is crucial to prevent leaks, ballooning, or other failures. Consulting with hydraulic hose suppliers or industrial tubing specialists can help identify the most suitable tubing option for your specific requirements.

ACE Hardware offers clear fuel lines that won't harden or discolour
Clear tubing can be used for fuel lines, but it is important to ensure that the tubing is specifically designed for that purpose. Some clear tubing, such as vinyl tubing, is not suitable for fuel lines as it can be damaged by ethanol and may harden, crack, and leak over time.
ACE Hardware offers clear fuel lines that are designed to withstand the chemicals in gasoline and ethanol, and they won't harden or discolour. This is a great option for those who want to be able to see the fuel flowing through the lines, such as when troubleshooting or inspecting for blockages.
The ACE Hardware clear fuel lines are a popular choice among owners of vintage bikes and lawn mowers. They are known for their durability and resistance to hardening or discolouration, even after extended use. This is especially important for fuel lines, as hardening can lead to cracking and leaks, which can be dangerous.
While some clear tubing options may need to be replaced frequently due to hardening or discolouration, the ACE Hardware fuel lines are designed to last. This can save time and money in the long run, as well as provide peace of mind knowing that your fuel lines are reliable and safe.
It is always important to follow the manufacturer's recommendations and guidelines when selecting and installing fuel lines to ensure safety and proper function. Consulting with a professional or experienced individuals in forums can also provide valuable insights and advice on choosing the most suitable fuel line for your specific needs.

Silicone gas line, used for model airplane fuel lines, is another option
When it comes to choosing a fuel line, there are various options available, including clear tubing. Clear vinyl tubes, for instance, can be used for chemicals, gases, and greases, but their suitability for gasoline is questionable. While some have used vinyl tubes without issues, others have experienced hardening and cracking over time. It is important to note that using a fuel line not rated for gasoline may pose a fire risk.
Brodak Manufacturing offers a heat-proof silicone fuel line that is small and ideal for model airplanes. It resists tearing, will not melt, and maintains its flexibility. This type of tubing is commonly used inside fuel tanks and can be placed directly against the engine without any issues.
Another option is the SIG Heat-Proof Silicone Fuel Line, which is also designed for glow fuel and not gasoline. This tubing is known for its durability and resistance to tearing or cutting. It can be used in direct contact with the engine, even the hottest parts, without any adverse effects. The required tubing diameter depends on the fuel fitting size on the engine.
Nitro Line Silicone Fuel Tubing is yet another option that offers high-quality silicone tubing with a 3/32" (2.38 mm) inner diameter.
