Returnline

[SIZZLESHANK]

Hello everyone. Im hooking up new gas lines and i have a few questions.

1. Where is the return line? I see a nozzle on the fuelrail where the fuel enters is that it? I just want to be 100%

2. Theres a tiny nozzle at the end of the fuel rail near the radiator what is that? And a nozzle to the right whats that?
(Neither of these have hoses connected to anything)

3. The original return line was on the evaporation canister do i use that?

All the unplugged nozzles are throwing me off id really appreciate an explanation and where to put this
