Does anyone know what the correct size (inside diameter) rubber fuel line is for my slant six 1974 Duster? I'm replacing the short segment in the engine compartment that connects the steel gas supply line (from the gas tank) to the inlet port of the fuel pump. This segment is about 8 inches long and is secured at either end with Keystone crimp clamps. I looked but can't find this info in my FSM. Thanks!
 
Thank you, sir. I'm assuming that I just use normal rubber fuel line, not the high pressure stuff used in fuel injection systems.
No you don't need the high pressure stuff, but there's a line right under that that's still low pressure, but ethanol friendly. I'd use that.

Got it - thanks.
