How does stainless steel with Teflon lining improve fuel system durability?

Stainless steel tubing resists rust and physical damage that can cause leaks in older rubber lines, while the Teflon inner layer resists chemical attack from modern fuels. Together they reduce swell, hardening, and permeation, which extends service life and helps maintain consistent fuel pressure.

• Corrosion resistance reduces risk of pinholes and leaks
• Teflon inner bore resists fuel additives and ethanol blends
• Improved long-term dimensional stability for reliable flow

What comes in the package and what do I need for installation?

The kit ships with two stainless/Teflon lines—a feed and a vapor line—plus the essential mounting hardware required for a typical replacement. Basic hand tools and a safe method to relieve fuel system pressure are all that’s needed, though professional installation is recommended if you’re unfamiliar with fuel system work.

• Included: SS/Teflon fuel feed line and SS/Teflon vapor line
• Included hardware: five steel/rubber clips, nuts, and screws for mounting
• Recommended: hand tools, fuel-pressure relief, shop manual or vehicle-specific guidance

How quickly should I replace my existing fuel lines and why?

Replace fuel lines promptly when you notice signs of wear, corrosion, or leakage to prevent fuel loss and reduce fire risk. Proactive replacement restores factory routing and connection integrity, which keeps the fuel system functioning as intended.

• Replace if you find rust, cracks, or visible fuel seepage
• Timely swaps prevent secondary damage to nearby components
• Restores original routing and secure mounting points
