Fuel line size

[White_4x4Ranger]

Hello, I’m wondering if anyone knows what the inner diameter is for the rubber fuel line between the fuel filter and the metal hard line on a 2003 ranger 4.0?

I'm pretty sure it will be 3/8"

5/16” and 3/8” were what Ford commonly used for fuel system on these trucks. I’m surprised you have rubber and metal, all the ones that I’ve seen with factory fuel systems used nylon line

I’m also moving this thread…

I thought... but i could be wrong... that all the high pressure nylon fuel lines were 5/16.
