Tha actual reason not to use copper is the maliability of copper will weaken the tube from vibration and cause catistrophic failure. You will not find anyone in the racing industry using copper fuel lines. You will however find aluminum. Aluminum works great and will not break from vibration. Stainless steel are nice too!
I run Aluminum with AN fittings everywhere. Supply and return. |

Dead soft aluminum is OK in the vibration dept, however I used T-2021 alumininum (hard) on my plane and found both lines were cracking on the first annual inspection. It was very evident after magnafluxing the tubes. Actually it scared the shit out of me. I replaced them w/ dead soft alum and flew it for the next 10 yr's w/o any signs of fatigue |
