These materials can withstand the constant temperature fluctuations and engine vibrations without losing their shape or becoming brittle. Look for fuel lines with a reinforced construction, as this added strength can enhance their flexibility and resistance to cracking.

During the inspection, pay close attention to any bends or curves in the fuel line route. The PCV valve is usually located near the engine's intake manifold, and the fuel line must navigate around various engine components. Ensure that the fuel line is routed in a way that allows for natural movement and does not impose unnecessary restrictions. Any sharp bends or kinks that could restrict movement should be avoided to prevent the fuel line from becoming stressed over time.

Additionally, consider the overall length of the fuel line. Longer fuel lines may require additional flexibility to accommodate the increased distance between the fuel source and the PCV valve. Longer lines can be more susceptible to movement and expansion, so ensuring they are made from flexible materials is essential. By verifying the flexibility of the fuel line through careful inspection and consideration of its material, construction, and routing, you can ensure that it can effectively accommodate the PCV valve's movement without the risk of cracking or breaking.

Length and Routing: Confirm fuel line length and routing allow easy access to PCV valve
