Reservoir or vapor tank?

The plastic tank on the rear passenger side.  It’s from the top left plug

Yeah, that's the vapor tank. Look at the original vapor tank plumbing and see what has been changed. That should make it clearer where that line came from. Fuel vapor is much more dangerous than liquid fuel and it's heavier than air. So it can collect in low areas and be set off by an ignition source.

oh boy....now you have me worried.....I saw one open line that connects to a  pipe that goes towards the engine,.   I t was just a line that was attached but cut short.   The other line from the vapor tank was no where near that line so i bought a 2 ft line and connected... hoping that was the missing line....that was the only other line that was not connected to anything?

I cant seem to find where the end piece goes....in the manual it just shows the end

That tube should make it's way to the engine compartment and connect to your "flow guide valve".

It's a predecessor to the carbon canister and is intended to store fuel vapors inside the engine crankcase while the engine isn't running.

Sorry for my ignorance ...but is this the flow guide valve?

If I remember right, there are four hard lines in the tunnel:

fuel supply

fuel return

rear brakes

vapor line

You will need to trace them to figure out which of the hard lines is for the vapor
