The best fuel line for small engines is called Viton, which is resistant to today's fuels
Another popular option for small engine fuel lines is Tygon. Tygon is a flexible, durable, and transparent fuel line that is easy to work with and allows users to see if fuel is flowing through the line. It is more expensive than other options but is known for its resistance to ethanol and its ability to hold up over time without rotting. Tygon is a good choice for those who want a fuel line that is easy to install and maintain, while still providing durability and performance.
When choosing a fuel line for a small engine, it is important to consider the inside diameter of the hose. Small engine fuel lines typically have an inside diameter of 1/4 or 3/16 inches. It is also important to avoid using hoses that are suitable for vacuum lines or windshield washer systems, as these are not designed to handle the high pressures and temperatures of a fuel system.
In addition to Viton and Tygon, there are other options available for small engine fuel lines. Some users recommend using motorcycle fuel lines, which are strong, less bulky, and suitable for most fuel applications. Others suggest purchasing fuel lines from local shops or online retailers like Amazon, which often come with clamps and filters included. Ultimately, the best fuel line for a small engine will depend on the specific application and the user's preferences for performance, durability, and ease of use.
