Fuel lines

hey guys
Does someone know the nhra/ihra fuel line specs for cars running 9.99 or faster? I have aluminum lines on mine now but i think i was told i had to up grade to braided lines and fittings below 10.0.

thanks to all replies........ron

I get to feel the torque of a BBF 4 times an 1/8 and 5 times a 1/4.

Lines: All non-OEM fuel lines (including gauge and/or data recorder lines) must be metallic, steel-braided or FIA accepted "woven pushlock". A maximum of 12-inches (30.5 cm) total (front to rear) of non-metallic or non-steel braided is permitted for connection purposes only; individual injector nozzle and motorcycle fuel lines are excluded. Fuel lines (except steel braided lines) in flywheel/bellhousing area must be enclosed in a 16-inch (40.6 cm) length of steel tubing, 1/8-inch (3.2 mm) minimum wall thickness, securely mounted as a protection against fuel line rupture. It is mandatory that fuel lines passing supercharger drive belts be steel braided or be enclosed in protective steel tubing. Fuel lines must not be routed in the driveshaft tunnel.
Aluminum falls under metallic lines, so you're good.
