While I was working in the trades, what I would have done was to locate the source of the leak, cut the line with a tubing cutter and insert a short section of line using 2 unions. If the repair doesn't leak, I use soapy water in a spray bottle, you're good to go.
I wouldn't go through all the trouble to replace the entire line.
Call Freightliner in Gaffney, SC and they should be able to provide you with an air line routing schematic.
Freightliner will be joining us soon by sponsoring the Freightliner Owner's Forum and I expect that that type of information will be made available or the means to get at the information will be presented.
