Frequently Asked Questions
Fuel lines typically last 10–20 years, but factors like driving conditions and exposure to corrosive elements (e.g., road salt) can shorten their lifespan.
Replacing fuel lines can be complex if you need to cut, flare, or bend them. However, our pre-bent, direct-fit fuel lines simplify installation, making it easier for DIY mechanics with the right tools.
The correct fuel line size depends on your vehicle’s make and model, as well as your engine’s fuel demands. Most stock vehicles use 3/8-inch or 5/16-inch fuel lines, while high-performance applications may require larger-diameter lines to handle increased fuel flow. SS Tubes offers multiple sizes and custom options for an exact fit.
We offer a range of fuel system components, including:
- Fuel Hoses & Rubber Fuel Lines: For flexible connections and repairs.
- Fuel Tank Sending Units: To monitor fuel levels accurately.
- Fuel Coolers: To maintain proper fuel temperature and prevent vapor lock.
- Fuel Tanks: Replacement tanks for various makes and models.
Switching to stainless steel fuel lines has many benefits over rubber or nylon options. Rubber lines wear out over time, but stainless steel resists rust and corrosion, making it last longer. The smooth tubing provides consistent fuel delivery without restrictions, helping the engine run better. It also holds up against extreme temperatures, preventing expansion, contraction, and leaks. These fuel lines work with modern fuels, including ethanol blends like E85, gasoline, and diesel, without breaking down.
