Where else can you buy aluminum fuel line in the size and length you need? This easy-to-flare and bend tubing works great as AN hard line and will save weight and money.

  • Use with tube nut couplers, sleeves and 37° flared AN fittings
  • Rated to 250 psi
  • Not recommended for high pressure (brake) applications
  • Available in 10 ft., 20 ft., or 30 ft. coils

Learn more about flaring hard lines and how to select proper automotive fittings by reading our tech article, The Principles of Automotive Fittings.


The main issue when dealing with aluminum tubing (or any aluminum for that matter) is that it “work hardens” when it flexes, which can lead to cracks. It is important that the hard line is isolated from vibration and movement.

Clamp the tubing securely with rubber coated clamps (Adel clamps) and use bulkhead fittings where the tubing attaches to the flex line. Never run the tubing directly to the engine without a flexible hose section. If installed properly, aluminum tubing is safe and durable.

Some parts are not legal for use in California or other states with similar laws/regulations
