1984 Stock Duke Vacuum Line Sizes (Page 1/1) cashmgr MAY 01, 12:43 PM Hi Guys, There is a lot of information about the v6 vacuum lines; but I cannot locate much on the Duke lines other than the routing diagram. Does anyone know what the hard and soft line sizes are for a complete replacement on my '84? I would rather buy bulk line in the right sizes in lieu of pulling all existing lines, marking locations and having the parts guy match them up. Length is not important as I always buy extra line as it is cheap and I'll have it for any subsequent replacements.. Thanks!
