Braided fuel lines weep. 1984 300TD turbo

[mybenz123]

Hello all.

I have a 84 300tdt and the braided fuel lines going
from the fuel tank to the overflow tank are weeping fuel.
I would like to replace them but don't know
which ones to get.
Fastlane lists a few different size fuel hose.
Which one do I need?

Any help is appreciated.

Louis.
