What You'll Learn
Rubber fuel lines are generally safe for everyday cars
Rubber fuel lines can handle the typical heat and pressure found in a car and are also resistant to damage from petroleum-based fuels. They are a good choice if you are on a budget or need several hoses, as they are cheaper than PTFE hoses and still work well. Rubber hoses are also easier to bend and fit into tight spaces, which is an advantage over PTFE hoses.
However, it is important to note that rubber fuel lines can deteriorate over time and may need to be checked more often as they can wear out. They are also not as durable as metal fuel lines, which are more resistant to wear and tear and are not prone to cracking or deterioration. Additionally, rubber fuel lines may not be compatible with certain fuels or chemicals.
To extend the life of rubber fuel lines and maintain safe fuel delivery, it is recommended to route them away from high-temperature components like exhaust systems or engine parts. Using fuel line insulation products, such as sleeves or wraps, can also help protect rubber fuel lines from heat sources and prevent damage. These insulation products are flexible and can be wrapped around the fuel lines to provide excellent heat protection and ensure optimal fuel performance and safety.

PTFE hoses are best for high-performance cars
When it comes to high-performance cars, the fuel line material can significantly impact the vehicle's overall performance, safety, and longevity. PTFE (Polytetrafluoroethylene) hoses offer several advantages over traditional rubber fuel lines in these high-performance applications.
Firstly, PTFE hoses excel in temperature resistance. They can withstand significantly higher temperatures than rubber fuel lines, making them ideal for high-performance engines that generate substantial heat. This temperature resistance also contributes to the safety of the fuel system by reducing the risk of heat-related failures or leaks.
Secondly, PTFE hoses provide superior chemical resistance. They are highly resistant to a wide range of chemicals and corrosive fuels, such as E85, that are commonly used in high-performance vehicles. This resistance ensures the longevity and reliability of the fuel system, even when exposed to aggressive chemicals.
Additionally, PTFE hoses offer enhanced durability and pressure resistance. The multi-layer construction of PTFE hoses, typically including an inner layer of PTFE, a middle layer of stainless steel braid, and an outer layer of nylon, provides exceptional strength and durability. This construction enables PTFE hoses to handle high-pressure conditions, ensuring a safe and reliable fuel system even in demanding applications.
While PTFE hoses are generally less flexible than rubber hoses, making installation in tight spaces more challenging, they are an excellent choice for high-performance cars due to their superior temperature, chemical, and pressure resistance. PTFE hoses enhance fuel flow, reliability, and safety, making them the preferred option for racing vehicles and modified engines.

Rubber fuel lines are known for their flexibility, making them ideal for installation in tight or hard-to-reach spaces. They are easier to bend and fit compared to PTFE or metal lines, especially in cramped engine compartments. This flexibility also contributes to their durability, as they can withstand the vibrations and movements of the vehicle without cracking or leaking.
The installation process for rubber fuel lines is generally simpler and more straightforward. Their pliability allows them to be manoeuvred into place without the need for complex connections or fittings. This ease of installation can save time and effort, especially when working in confined engine areas.
In terms of cost, rubber fuel lines are usually less expensive than PTFE or metal lines. They are widely available and can be a good choice for those on a budget. Additionally, rubber fuel lines are designed to safely transport gasoline and other fuel types. While they may not have the same heat resistance as PTFE, they can handle the typical heat levels found in a car's engine bay.
To enhance the heat resistance of rubber fuel lines, various protective measures can be implemented. Fuel line insulation products, such as sleeves or wraps, can be used to shield the rubber lines from heat sources. These products are designed to redirect heat away from the lines, maintaining optimal fuel performance and safety. Proper routing of the fuel lines away from high-temperature components, such as the exhaust system or certain engine parts, can also help extend the life of rubber fuel lines.
