Eric,
Please come back down to Planet Reality.

You don't have to change fuel lines and/or move anything.
The SVT and non-SVT variants have IDENTICAL fuel lines, and the exhaust comes nowhere near them anyway. In any case they are steel lines, so unless your exhaust somehow is glowing red-hot and setsthe underside of the car on fire by some freak occurance - your concern is unwarranted.
Find someone who knows their ass form a hole in the ground to install you ehaust or do it yourself. Sounds like they were feeding you a line a crap to get more money out of you or they just didn't want to do the job.

The only difference in the SVT-and non-SVT is the fact that the SVT has an extra muffler hanger on the pass. side. All you need is to buy this part from the dealer (or get an exhaust shop that is good to make uone up)and you can hang ANY SVT exhaust on a non-SVT.
