I have done 3 trucks in the past year. I have done all with rolls of tubing and Harbor freight tubing bender and flaring tool, except for the last one where I borrowed my buddies $500 plus MAC hydraulic flaring tool. The hydraulic tool made flares perfect flares in under 1 minute, it took alot more patience with the HF tool, but it did the job. Here is my take. If you want all the lines in the exact same spot run the exact same way get the pre bent line. I ran all the new lines in the inside of the frame rather than on top. Do all the front lines at the same time, it is easier than working around the already brittle lines and also easier rout them closer to stock positions. Almost 100% you will need to replace the rubber lines too so expect that. Be ready with heat to get every bleeder out and to replace them too, be ready for bleeders to snap off and to replace the calipers. 1 roll of tubing will not be enough for all the front lines since the 2 master lines go to the ABS pump and then back up to the caliper. Spray PB blaster or such on the ABS pump fittings several times days before and use the proper flare wrenches to take fittings off. Bleeding the brakes can be a SOB. I made a power bleeder out of an old master cap to push fluid through. I had trouble with 1 truck. Be prepared to get dirt and get rust in your eyes even with safety glasses on it is a cruddy job, but really can be done in a day from start to finish, especially with a little help.
