I think the question was also wrong

So, just to clarify, the right one that runs from the regulator is the return line. The left one (red) is a vent line. The feed line is not pictured, it is on the other side of the rail and is coming up from the fuel filter on the right side of the car. At least on mine, which is a 99 Base.

Ha! What a rollercoaster. Join us next week for: What are these “coolant” lines?
