FAQS
Rubber fuel lines are generally more affordable and flexible, making them suitable for low-pressure applications. However, they are susceptible to degradation from exposure to fuels, especially ethanol blends. PTFE (Teflon) lines offer superior chemical resistance, temperature tolerance, and durability, making them ideal for high-pressure and demanding applications, although they are more expensive and less flexible. Selecting the appropriate material depends on the specific fuel type and operating conditions.
The recommended replacement interval for fuel lines varies depending on the material, operating conditions, and manufacturer's recommendations. As a general guideline, rubber fuel lines should be inspected annually and replaced every 5-7 years.
