300SD Metal Fuel line

Submitted by fuentes_ed on 8 May 2008 - 2:37pm.
Hi... I have a diesel leak on my 1981 - 300SD...surprised :) Well its not at any of the rubber connections its at a bend in the metal fuel line under the car. I rather not replace with rubber so I've been trying to find a flair tool and pipe bender - which I have. I need to know what size of metal fuel line to buy. Does anyone know? Any help would be appreciated - THANKS ED
