Fuel line

[Abarth124]

Hi, can somone tell me which line is the fuel supply line and which one is the fuel return line?

I think the curved line is the supply line, am I right? Thx.

I need to which lines are which coming out of the firewall.

Oh, and the supply line would connect to the rear of the fuel rail, and the return line would connect to the bottom of the fuel pressure regulator, is this right? Any suggestions would be helpful. Thx.

On my wrecked 81 and my running 82 the bottom fuel line coming out of the firewall is the supply line going to the rear of the fuel rail.
Hope this helps,
