Here's a few pics of the brake line route on my '71.
Pay no attention to the unplugged wire above my oil pressure sending unit. My sending unit developed a short - causing the guage to read "full on". I'm switching to a mechanical system soon. The sending unit wire was renewed, but I do believe the short is in the actual sending unit.
