Returnline

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

I did some research figured stuff out what the tiny nozzle was. (fuel pressure regulator)

This is the nozzle im talking about https://imgur.com/b4utAFD it goes into the intake manifold

This is my fuel pressure regulator https://imgur.com/2ydmed3 That stem, goes it plug into the fuel pressure regulator at the end of the fuel rail or here https://imgur.com/GUh3hHw

Last question Can I use the cars preexisting wiring to connect my electric fuelpump?
