Does anyone know,or have they run Russel twist lok hose(or Aeroquip&such) for their fuel system.I am using braided stainless steel line for the fuel delivery side,but want to use the russel line on the return side of the system.This is for a carb'ed car,so pressure at max with juice will be no more than around 8-10 psi.Any help is greatly appreciated!

General regulations 1:5

All non-OEM fuel lines must be metallic, steel braided or NHRA accepted "woven pushlock". A maximum of 12 inches total of non-metallic or non-steel braided hose is permitted for connection purposes only.

NHRA accepted woven pushlock fuel line: Aeroquip FC300 and Aeroquip Star Lite 200.

Now nothing is stated if the lines are supply or return so assume the entire fuel system falls under the above rules.
