However, it also means that the lines can be more susceptible to kinking, especially if the vehicle has a low ground clearance.
• Avoidance of Heat Sources: Fuel lines should be kept away from heat sources like exhaust systems, engine components, and under-hood components. High temperatures can cause the fuel lines to degrade and become brittle, leading to potential leaks and fuel contamination.
• Secure Mounting: Properly secure the fuel lines to prevent excessive movement. Use appropriate mounting points and brackets to ensure the lines remain in place and do not rub against other components, which could cause damage or wear.

Best Practices for Fuel Line Routing:

• Route the fuel lines as close to the fuel tank as possible to minimize the length of the line, reducing the potential for kinking.
• Use flexible fuel lines with a suitable diameter to accommodate the fuel flow rate and ensure smooth bending.
• Consider using a fuel line protector or shield to guard against sharp edges and potential damage.
• Regularly inspect the fuel lines for any signs of wear, damage, or kinking, especially in areas where the lines are more susceptible to impact or heat.

By implementing these routing practices, you can ensure that your fuel lines are properly protected, preventing kinking and maintaining a consistent fuel supply to the engine.
