Fuel System Help

So bare with me, I'm new to this
I bought my Duster and it had and electric fuel pump mounted on the rear frame plumbed inbetween the existing lines of the gas tank and the origianl metal line that runs up to the engine bay.
I'm not sure what fuel pump it is, but its leaking, and has always been very loud. I think its a summit brand (thats whats on the mounting hardware) and has what looks likes a metal base plate
bolted to the bottom of it with a rubber gasket under the plate, thats were its leaking. I tried to tighten up the bolts but no dice.
Anyway, looking to get a new pump and possible run a return line but i'm not sure the correct (read safe) way to do this.
I have a vent line that looks to be unused, it runs along with the feed line into the engine bay but is not hooked to anything. Can I use this for a return line? and should I plumb it into the piece
of hardware i've outlined below ( the regulator I believe) Like I said, this is new to me.

you cannot use the vent line to return fuel back to the tank. the vent line is just that. a vent. you can use it IF you vent the tank another way. alot of the cars came off the production line with a vent line that ran up the filler tube on the inner quarter panel. you could make something like that pretty easy. as for the return line. you cannot run it right off the pressure regulator. your system will just create a loop and pump fuel back to the tank. you need the return line to come off the rearmost portion of the fuel rail on carb.

got it, thanks. So it looks like I need a different fuel rail to be able to even run a return line eh?

yes. a fuel rail that has an outlet on the rear. that alows the carb to take what it needs and the rest is fed back to the tank.

This isn't entirely true. There are several return style regulators that can be used deadheading the carb. (Aeromotive 13301 comes to mind). I've done it numerous times. My preference is to put the regulator on the return side, but it isn't always a practical option.

My god I have never seen so many wires under a hood before!

I know, tell me about it. That's right after I bought it. It does not look like that anymore...
The PO had all the wiring 'professionally' rewired and the fuse box ended up under the hood.. This is a picture of it part way through putting the engine bay back together..
