fuel line routing question, can't remember Options

[metalmorphosis]

I need some help remembering how exactly the fuel lines go. The car is a 73 1.7 w stock fuel injection and pump in stock location. The pump has a S, D, and R on it and I'm pretty sure thats obviously supply, divert, and return. So my 1st question is where does the D or divert line goto? The 2nd question is that it looks like once the supply line gets to the engine it 1st goes across to the driver side to the regulator then to the fuel rails and back down to the return side of the pump is this right? Thanks in advance for any advice and/or pics.

With the engine being removed is there a way to check fuel flow?
I have disconnected the harnest going to the pump and supply it 12 volts. I hear it working but no fuel comes out the lines (regulator and injector rail line). I have tripled checked the lines and have even compared it to this diagram and it seems to be hooked up the right way. I can also see a small amount of fuel in the clear lines by the firewall. I don't know if using a universal filter is make the difference, but I am using it (which I have also trippled checked the flow direction and its good).
As it stands right now, tank to lines, (1) line to filter, filter to pump, (2)pump return to "T" spliter to 8mm line, 1 of the "T" tines is out in the open, the injector line is also out in the open. Should I have something pluged up or removed to get fuel to flow? (IMG:style_emoticons/default/confused24.gif)
