I suspect the lines on my 47 are not stock and I want to keep it all stock. One of the lines ruptured along the frame rail. Thanks for all the great help in the past! | | | | | Joined: Oct 2010 Posts: 10 New Guy | | New Guy Joined: Oct 2010 Posts: 10 | The line is 1/4 inch for all the hard lines on the 47. I found this out after removing all the brake lines. Some were 3/16 and the most were 1/4 inch. There was a long section of compression fitting pipe along the frame rail to the rear. What a mess! | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | i have kind of the same problem...my 48 gmc 1/2 ton came with all 3/16...i ordered prebent lines, and i got 2 lines 3/16 and 5 lines 1/4...HELP | | |
