Let me post the NHRA rule on non-metallic fuel line....this is from the 2009 Rulebook....
"All non-OEM fuel lines (including gauge and/or data recorder lines) must be metallic, steel braided or NHRA-accepted woven or woven-pushlock. A maximum of 12 inches total (front to rear) of non-metallic or non-steel braided hose is permitted for connection purposes only; individual injector nozzle and motorcycle fuel lines are excluded."
The aforementioned woven and woven-pushlock was last published in the 2008 Rulebook as follows:
"Aeroquip FC300, FC322; Aeroquip Starlite 200; AQP Socketless; Earl's Prolite; Fragola Performance Systems Series 8000 Push-Lite Race Hose; Gates LOL Plus; Goodridge 536, 710; Russell Twist-Loc836 and XRP HS-79; Dayco Imperial Nylo-seal tubing."
I'm still unsure if there is actually a "Goodridge" or if it's a typo for Goodrich.
It seems that there is a problem for the OEM manufacturers in countries where high concentrations of ethyl alcohol (ethanol) are used and we are probably headed down the same pike in this country. We already have E85 available at the pumps in many areas of the country and will probably see more, with the current liberal Democratic Congress and Democratic President at the helm. Check out this short paper from the Society of Automotive Engineers.....
The end-all of fuel lines has always been considered to be stainless steel. Stainless braided works also, but you need to be careful about the liner used to manufacture the stainless braided to make certain the liner is compatible with ethanol. Surprisingly, I found out by doing some searching about compatibility, that copper is very compatible with ethanol. So, using copper fuel line would seem to be the best and cheapest answer if you're totally re-plumbing your ride. Copper will work harden and crack from vibration though, so it must be secured well to the frame or a frame member or other suitable part of the vehicle all the way along its run from the tank/cell to the carb/injectors.
