There's two reasons I can think of. Either the stock line was damaged that it was easier to run a new line. Or the fuel system was upgraded at some point. Are you not able to contact the shop?
The fuel system is upgraded all around, however I have stock rails, stock feed/pressure line, and a nylon braided return fuel line. I just cant understand why, please help me as it makes no sense to me.
Might want to do some more research, since yes in fact mid year 98 Ford moved to a returnless style fuel system. As far as why you have braided line? Who knows, most likely parts availability. Regardless, if it isn't leaking, and you aren't experiencing fuel issues, no point getting worked up over a non-issue.
Welcome to the joys of buying a modified used car. A world where previous owners do things that make us scratch our heads and wonder what drugs they were on. All you can do is fix whatever they did and move on.
So then you should be able to answer your own questions. And you should know which shop did whatever work to it. So they would be the ones to ask.
You are correct but I dislike the shop so im changing shops. No shop turns my wrenches only me. I only use shops for dyno tuning, but sometimes they jew their ways into working on my car and just damage it with shitty subpar work everytime. I dont bash shops so I dont mention them.
