Ok, so I want to install stainless steel fuel lines in the center tunnel of my turbo type-4 912 project. At each end of the hard line I want to go to braided line with AN fittings, to the fuel pump and tank in the front and to the engine bay in the rear. I planned to run 3/8" pressure line, 5/16" return (can be 3/8" if it needs to be), and AN-6 braided line everywhere else. My issue is the compatibility of all the different fitting options to go from the hard line to the braided lines. I do not want to use any hose clamps or anything and I want it to look nice. I have researched the various AN fittings, pipe fittings, NPT fittings, Swagelok fittings, flare fittings, etc. and I have looked into different types of hard lines. Can someone give me a simple solution to do what I want to do. I know that there are people how have installed hard lines and braided lines in there cars, someone has to have an easy solution.
