Front passenger side vacuum line??

Can not figure out where this line goes? When I took it off 7 years ago I marked it, but can't seem to get it correctly positioned. Need an expert

The fuel line from the fuel tank comes up the passenger side of the car along the passenger frame rails. Often times there are two fuel lines. A 5/16 (or 3/8) fuel supply and 1/4 return line.

It think it could be the line from the fuel tank vapor saver system. It runs back to the vapor/liquid separator mounted in the trunk.
The liquid separator has 5 lines that come out under the car behind the rear wheel well.
4 go to the fuel tank 1 comes to the engine bay pictured in the previous post.
The plated line shown in the previous post connects to the 3 nipple breather cap in the rocker cover.
As far as I know the 340 cars did not have a return of liquid fuel to the fuel tank. Only big block high performance cars with the factory fitted inline fuel/vapor separator got the third line running back to the fuel gauge sender unit.

Now seeing where the goes. Need to figure out, what they connect to. The engine is a 318

You can't just show us a teaser. You should start a new thread and tell us/show us more of your Challenger.

It is a Barracuda Gran Coupe. Had some pics up when I joined last month. Wish I had someone here to help me get it running. Really close.
