The heat resistance of fuel lines is an important consideration for many vehicle and machinery owners. Some materials, such as Tygon hose, have very low resistance to heat and may not be suitable for certain applications, such as chainsaws. Silicone tubing is known for its heat resistance and is often used as a fuel line that can come into contact with hot engine parts without melting or being affected. Other options include stainless steel, rubber, and PVC.

What You'll Learn
Silicone hose ratings
Silicone hoses have a temperature rating of 300°F and higher at low pressures. They are capable of carrying fluids at much higher temperatures than rubber and are ideal for racing vehicles or turbochargers. The maximum temperature they can withstand is 350°F (177°C), while standard EPDM rubber hoses have a maximum temperature of 257°F (125°C).
Silicone hoses have superior flexibility and maintain this flexibility over their lifespan, while rubber does not, reducing the risk of splitting, exploding, hardening, or dry rot. Silicone hoses are also extremely inert and resist chemical reactions with other substances, so they won't corrode or adhere to surrounding parts. They are also resistant to environmental factors such as rain, snow, heat, humidity, drought, UV rays, and ozone, which makes them a great choice for vehicles driven in harsh environments.
However, it is important to note that silicone is not compatible with fuel, oil, or other oil-based products. Silicone hoses are watertight, but water vapor can escape slowly through the walls of the hose. This means that if you have silicone hoses on a daily driver, you may need to occasionally replace the water in the reservoir, even if there is no leak.
Some silicone fuel lines are specifically designed for glow fuel and not gasoline. These products will not harden in fuel and can touch any part of the engine without being affected.

Rubber fuel lines
To ensure the safe fuel delivery of rubber fuel lines and extend their life, it is essential to protect them from heat sources. Whenever possible, route the fuel lines away from high-temperature components such as exhaust systems or engine parts. Additionally, fuel line insulation products like sleeves, wraps, or heat shields can be used to shield rubber fuel lines from heat. These products are available in various materials, including fiberglass, reflective foil, and thermal-resistant fabrics, and can provide excellent heat protection for rubber fuel lines.
The temperature rating of rubber fuel lines is important to consider. While the exact temperature resistance of rubber fuel lines may vary depending on the specific material and construction, some sources suggest that a silicone hose rating would be 300°F or higher at low pressures. It is worth noting that most "rubber" materials are maybe half to two-thirds as resistant to heat as silicone.
To enhance the heat resistance of rubber fuel lines, insulation wraps or sleeves made from heat-reflective materials can be used. These products can redirect heat away from the lines, ensuring optimal fuel performance and safety. It is also important to ensure that the fuel lines are securely mounted and well-protected to prevent abrasion and contact with sharp objects, which can compromise the integrity of the lines.

Tygon hose
Tygon® is a brand name for a family of flexible polymer tubing, consisting of a variety of materials. Tygon is a registered trademark of Saint-Gobain Corporation, a thermoplastic (plastic material) tubing. The tubing may be made of different plastic compounds composed of materials such as silicone, PCV, polyurethane, fluoropolymers, and thermoplastic elastomers. Tygon tubing is used in many markets, including food and beverage, chemical processing, industrial, laboratory, medical, pharmaceutical, and semiconductor processing.
Tygon tubing has numerous unique physicochemical properties, including transparency, flexibility, crush resistance, resilience, chemical resistance, smoothness of the inner surface, and adequate gas permeability. It is also non-hemolytic, non-toxic, and biocompatible. Tygon tubing is available in Plasticizer-free/non-DEHP (non-Phthalate)-formulations, which have a high degree of chemical resistance and do not release any hazardous material when properly incinerated.
Tygon tubing is designed for peristaltic pump use, offering softness, flexibility, resistance to compression, and fatigue strength. The rated working pressure for Tygon tubing is determined using a safety factor of 1:5 against burst pressure at room temperature, 23°C. As the temperature increases, the working pressure can decrease. The maximum working vacuum at room temperature is given for most Tygon tubing.
Tygon Fuel and Lubricant Tubing F-4040-A is used in small engine fuel lines, recreational vehicles, and lubrication lines. However, it is important to note that Tygon hose has very low resistance to heat and may not be suitable for replacement hoses on some machines.

Vapor Block™ fuel line sleeve
Fuel lines are designed to withstand high external/ambient air temperatures. However, the fluids inside the lines can boil due to extreme heat, causing a vapor lock situation. This can lead to rough idling and difficult starting. The Vapor Block™ fuel line sleeve was designed to prevent this issue by reducing heat in the line and keeping the fuel temperature below boiling.
The Vapor Block™ fuel line sleeve is made of glass fibre and polyester laminated to an aluminium outer layer. This construction offers excellent thermal protection for fuel systems, ensuring long-lasting performance. It is easy to install, with a split design and adhesive flap that allows for quick and convenient application without the need to disconnect the fuel line. Simply wrap the sleeve around the line, remove the adhesive liner, and secure the adhesive flap.
The Vapor Block™ fuel line sleeve is available in different sizes, including 3/8" I.D. x 36" and 5/8" I.D. x 36", to accommodate various fuel line dimensions. It is a straightforward and effective solution, as noted by a customer who used it to thermal insulate the fuel lines of their '68 Mustang. They recommended the product for its ease of use and ability to prevent vapor lock.
Vapor Block™ is manufactured by Design Engineering, Inc., a family-owned US-based company. The company has over 25 years of experience in creating innovative solutions for heat and sound control across various markets, including automotive, RV, power sports, residential, and marine. Their commitment to delivering high-quality products makes Vapor Block™ a reliable choice for maintaining fuel system performance and preventing vapor lock-related issues.

Fuel line clamps
One of the most critical aspects of fuel line clamps is their ability to withstand high temperatures. The clamps must be heat-resistant to prevent melting or failure, which could result in fuel leaks and potential safety hazards. To address this concern, manufacturers often use high-quality materials such as stainless steel or silicone to construct the clamps.
For example, silicone fuel line clamps, like those offered by SIG Manufacturing, are renowned for their heat resistance. These clamps can withstand direct contact with the engine's hottest parts without melting or being affected. Silicone's high-temperature resistance makes it an ideal material for fuel line clamps, providing peace of mind and ensuring the safety of the vehicle's fuel system.
Additionally, fuel line clamps come in different sizes to accommodate various fuel line diameters. It is crucial to select the correct clamp size to ensure a secure fit and prevent fuel leaks. Some clamps, like the ones mentioned in the AutoZone source, are designed specifically for certain vehicle models, ensuring a precise match with the fuel system.
When it comes to purchasing fuel line clamps, it is essential to consider the quality and reliability of the product. Reputable manufacturers and suppliers, such as AutoZone and QFS, offer a range of clamps that meet industry standards and provide durable and dependable solutions. By investing in high-quality fuel line clamps, vehicle owners can maintain the integrity of their fuel systems and ensure safe and efficient performance.
