What are these lines
 

I understand the two inner black lines are power steering (in blue box), could someone tell me what the other 4 lines (in red box) are, ie the thicker black line with white plastic fitting, the thin blue rigid line, and the two outer thin lines (which go to some sort of metal junction box. Thanks

Fuel (black), clutch (blue), rear brake lines (black).

The thick black plastic one is vacuum for the brake booster. The two metal ones to the junction box are for the rear brakes. Correct that the blue one is clutch. Fuel lines are near the center of the car.

I second @78F350 response. I came back to change my post.
