Avoid running the lines alongside hot engine components or exhaust systems, as this can lead to fuel line damage or contamination. Instead, plan a route that provides a safe distance from heat sources.

Consider the engine's mounting points and available space when planning the route. You might need to use brackets or ties to secure the lines in place, ensuring they remain taut and free from any sharp bends or kinks. Aim for a layout that allows for easy access during maintenance and inspection.

The choice of fuel line material is essential. Opt for high-temperature-rated materials to withstand the engine's operating conditions. Flexible fuel lines with a protective outer layer are ideal, ensuring durability and resistance to heat and abrasion.

Pay close attention to the bends in the fuel lines. Avoid sharp bends, as they can restrict fuel flow and potentially cause damage over time. Instead, create gentle curves, allowing for a smooth flow of fuel. Use bends that are gradual and wide enough to prevent stress on the line.

Additionally, consider the use of fuel line protectors or sleeves, especially if the lines will be routed near the exhaust or other hot surfaces. These protectors provide an extra layer of insulation and help prevent heat-related damage. Proper routing and the use of suitable materials will ensure a reliable and long-lasting fuel system for your YS60 motor.

Fittings: Select compatible fittings for secure connections and leak prevention

When it comes to running fuel lines to your YS 60 motor, selecting the right fittings is crucial for ensuring secure connections and preventing leaks. The goal is to create a reliable and efficient fuel delivery system that can withstand the demands of your engine. Here's a detailed guide on choosing the appropriate fittings:

Material Compatibility: Begin by considering the material compatibility between the fuel lines, fittings, and your motor. Different materials have varying levels of resistance to fuel degradation. For instance, natural rubber fuel lines are commonly used due to their flexibility and compatibility with gasoline. However, if you're dealing with diesel or certain types of fuel, you might need to opt for fittings made from materials like nitrile or fluoropolymer, which offer better resistance to fuel-related chemicals.

Fitting Types: There are various types of fittings available, each serving a specific purpose. The most common types include barbed fittings, compression fittings, and quick-connect fittings. Barbed fittings are ideal for creating a temporary connection and are often used for testing or short-term applications. Compression fittings provide a secure, leak-resistant seal by compressing the fuel line against the fitting. Quick-connect fittings offer convenience and ease of use, allowing for rapid assembly and disassembly. Choose the fitting type that best suits your project's requirements and the level of accessibility you need.

Size and Thread Compatibility: Ensure that the fittings you select are compatible with the size and thread of your fuel lines. Fuel lines typically come in standard sizes, such as 3/8" or 1/4" ID (inside diameter). Measure the inside diameter of your fuel lines and choose fittings with matching threads. Using the wrong size can result in a poor connection, leading to fuel leaks or reduced performance.

Leak-Proof Design: Look for fittings that feature a robust, leak-proof design. This is essential to prevent fuel spills and potential hazards.
