Answer :
Final answer:
The claim that fuel lines in Common Rail Diesel systems are for one-time use only is false. These fuel lines are engineered for multiple uses, given that they can withstand high pressures and temperatures.
Explanation:
The statement that fuel lines used in Common Rail Diesel (CRD) systems are designed for one-time use only is false. Common rail diesel systems are engineered to allow for multiple uses of fuel lines. These systems require fuel lines that can withstand high pressures and temperatures associated with modern diesel engines. Fuel lines are typically made of robust materials that do not degrade quickly and can be re-used, provided they are not damaged or worn out.
