Ouch...I think I spent $900 for the lines at Classic and then items like the 2 fuel pumps, shocks, and some other misc items put the project tab at around $2K for me. The fuel lines were a bear on the burb because of the way they hug the frame rail, the torsion bars need to be released and slid out of the way.
Here is a shot of the fuel lines. Note that when the front fuel tank is installed, it goes right up against the frame and hides these lines from view,

Here are the brake lines where they cross under the frame rail coming forward from the ABS unit:

Cale good luck with the job...the dealer should be able to fabricate a crossover line pretty easily to go with the kit. Be advised I had to replace the rear calipers too because I couldn't get the bleed screws open....so you may have some additional costs to the job if other rusty parts break off when they are replacing the lines. When I had mine apart I had some time to hit the underside of the frame and body with the wire wheel and spray some rust converter underneath, topped with Rustoleum undercoating. Not a permanent fix but anything to help delay the inevitable.
I also sent the fuel injectors out to be ultrasonically cleaned and rebuilt with new pintles and O-rings and bench checked for flow balance. Along with a new filter the entire fuel system is new front to back. Should be good for a few years.
I will say I am jealous, I wish I had the $$$ to have this job done at the dealer, it's not something I would do again.
