The fuel hoses in a Jeep Liberty diesel are
not typically made entirely of rubber. While some older vehicles might have used primarily rubber fuel lines, modern vehicles, including the Jeep Liberty diesel, generally utilize fuel-resistant synthetic rubber or other materials like reinforced nylon or specialized polymer blends. These materials are designed to withstand the harsher chemicals and pressures of diesel fuel and last longer than traditional rubber.
Therefore, it's inaccurate to say they are *made of rubber*, but they likely incorporate some rubber-like components in their construction for flexibility and durability. To be certain of the exact composition of your specific Jeep Liberty's fuel hoses, you would need to consult a repair manual or the vehicle's specifications.
