Fuel line size from tank to fuel pump on my 1968 C10

Can anyone tell me what the stock size is for the metal fuel line routed from tank to pump is along the frame? (in cab tank). Thank you.

Not sure if it changed in 1972, but my stock 350 has 3/8" fuel line.

If it is a V-8 it would be 3/8".

Thank you, gents. I noticed the short section of hose from tank to line was showing signs of age. Wanted to make sure I had the right size to replace it.
