318 - Fuel Line Route

Rebuilt a 318 engine on a 68 W200. Changed the intake and added headers. New fuel pump and alternator.

Need to install a fuel hardline from the pump up to near the carb.

Also have a 66/67 W200 short bed with a souped up (period/vintage) 318 - intake, headers, Carter 4 barrel. The fuel line on it comes up from the pump inside the alternator bracket/behind the fan pulley. Have a 360 from a parts truck and the fuel line took the same route.

New fuel pump port angles do not match exactly the old pump ports and the alternator is different. Still thinking about taking the same rout with the new line, but thought I would ask for feedback here.

I never was a fan of the factory behind the alternator routing of the fuel line from pump to carb because I feel it can contribute to vapor lock problems in the Summer, at least where I live. I always route the line out away from the block/alternator & up over the passenger side valve cover. It might not look as clean as the original way though.
