One wonders if you were to show up at an NHRA track with your modern EFI rig and the stem--to--stern plastic fuel tubing, not to mention the tank itself, how all those rules sit.
[FONT="]Lines: [/FONT][FONT="]All non-OEM fuel lines (including gauge and/or data[/FONT] [FONT="]recorder lines) must be metallic, steel braided, or NHRA-accepted[/FONT] [FONT="]woven or woven-pushlock. A maximum of 12 inches total (front to[/FONT] [FONT="]rear) of non-metallic or non-steel braided hose is permitted for[/FONT] [FONT="]connection purposes only; individual injector nozzle and motorcycle[/FONT] [FONT="]fuel lines are excluded. Fuel lines (except steel braided lines) in the[/FONT] [FONT="]flywheel/bellhousing area must be enclosed in a 16-inch length of[/FONT] [FONT="]steel tubing, 1/8-inch-minimum wall thickness, securely mounted as[/FONT] [FONT="]a protection against fuel-line rupture. Fuel lines may not be routed[/FONT] [FONT="]in the driveshaft tunnel. It is mandatory that fuel lines passing[/FONT] [FONT="]supercharger drive belts be steel braided, NHRA-accepted woven[/FONT] [FONT="]or woven-pushlock, or be enclosed in protective steel tubing. A[/FONT] [FONT="]current list of NHRA-accepted woven or woven-pushlock fuel lines[/FONT] [FONT="]is available on NHRA.com. All NHRA-accepted fuel lines must use[/FONT] [FONT="]General Regulations[/FONT] [FONT="]Section 20, page [/FONT][FONT="]5 [/FONT][FONT="]General Regulations[/FONT] [FONT="]ends that are specifically designed for the type of fuel line being[/FONT] [FONT="]used. No hose clamps allowed on NHRA-accepted fuel lines.[/FONT]
