Started playing with the regulator mounting and carb feed lines. The inner fenders aren't in yet obviously, so out of curiosity I tried using one of the coolant overflow tank mounting holes to hang the regulator. With the length of the braided lines, it works pretty decent. I may leave it like this, since it would be easy to tube down, and out the back for the rest of the fuel line. The only problem is the lip of the cowl would make it hard to get an allen key into the regulator, but I could clearance just that spot, and you wouldn't really notice. Also would still have to put a tee in to run a fuel pressure gauge. I know the fpr isn't supposed to be on the firewall if I wanted the truck to pass tech, but since Calgary lost its track couple years back, i'd say chances are pretty slim.
