I've been having some fuel gelling issues which at this point I have under control. My question though is how the 24 valve fuel loop works... Its too cold to get under the truck and trace it out, but it would help me out visualizing the problems if I knew how it ran. I have a FASS HD pump that feeds the stock filter housing. Do these VP44's have a return tot he tank? or is the return from the stock filter? or no return?

Return is on the back driver side of the head, just below the valve cover.

The VP44 has a return line that goes from the VP, back to the head area, like 98whitelightnin said, and there is a tee where the injector return line ties into the VP return, and it all goes back to the tank.

Click the picture to watch. Pause it at 6:05, and you can see the return lines, and the tee on the right hand side:
