need some advice, running 3/8" fuel line, how to run, what to use

, but scary: trans. explosions, and driveshaft disintegration at 128mph cuts slicks and tears the hell out of everything under there.., why I put most of mine inside the frame rails and connectors, w/ exception of the return ,it`s braided ptfe .

True. We’ve got our fuel pump and filters tucked up and protected/shielded. 2 drive shaft loops, SFI trans case and SFI bellhousing. The lines as best protected as possible (not inside though ).
