I am running/trying to run the nylon/plastic lines on my Fox body and its great b/c it's 'cheap' but doesnt like bends and if it bends it will crimp and that section looks like it is not going to flow properly. I would say it would be much easier to run it on a truck frame than the mustang since there is actually places to run the line.
3/8" feed line and 5/8" return line.
U r going to need the fittings from dorman that click onto the hard lines. And you do not need the Dorman 800-300 unless you just want to spend that much money on that and if I was going to do ALOT of these then I would but I used a home made set up.
I will see if I can find the thread here that made the light go off but you basically use the clamp that's used for brake line flariing to hold the line and then you use a "caulk gun" to press the fitting into the line. Works pretty well if you have patience.
Hope that helps.
