The one that isnt coming from the fuel filter is the return line.

 

Oh. Well, this one comes out of the firewall, so i'll guess that it isn't it.

 

yeah probably not, nice fuel rail though.

 

That looks more like the airconditioner drip hose.

You need to remove the upper intake/dynamic chamber to see the hard return line that goes to the left side of the engine and then connects to a fuel injector spec return hose.

Find your fuel filter, there is one line coming from that for fuel send, there is another line NEXT to the filter that is the return line. It is directly next to it.

 

Ah, I see. Thanks a lot, guys. I think my fuel injector clips look a little shady, I'm not too sure if they're good to use.
