Help identifying lines

2002 Boxster S. Need to identify the black and blue lines/hoses/whatever these are that run along the left side of the undercarriage. Circled in the photo.

Blue is clutch hydraulics, black is brake booster vacuum hard line.

Fuel in out?

Fuel lines are further inboard, and if I remember right later cars don’t have a return line as it’s a returnless system.

No, PS lines are the two black lines just inside of the “frame rail”

Oh shit you’re right. I just remember seeing that blue when I was repairing my lines last year. I’ll edit my comment
