fuel lines/pump/routing

on my 82 T/A, i have a mechanical fuyel pump. anyone know how to route the fuel Lines? there's 3 nipples on the pump facing you as you look from the front. i thnk the middle goes to the carb, but what about the other two? one goes to the tank, but the third? and the carb.... it's an edelbrock 600 cfm. the fuel nipple is on the front, so I think it connects to the middle nipple on the fuel pump. anything else? if I knew of a site I could link to easily, i would host pics there and link em. all help is appreciated.

The large one pointing somewhat to the side is the inlet from the tank. The other large one is the outlet to the carb. The smaller one is the return line to the tank.

As installed, the middle one would go to the carb.

sweet. on my edelbrock carb, there's a large nipple on the front.. I'm assuming that's the inlet for fuel. there's another large one on the side (left side) near the top, towards the back. is that for fuel or vacuum for the butterflies?
