Without actually asking him, but I'll venture some guesses.
I think it probably involves a design choice really. Whoever designed the kit(Wyatt knows him) made the call to worry about a vacuum return to the back of the car rather than the fuel return line. Also, with the absence of a fuel return in 96+ cars, he must have just thought it would be unfeasible or rather uneasy to find a way to tap into the fuel rail in order to make the fuel return line. Maybe HRC was lucky enough to come to the realization of usign the service fitting on the fuel rail in order to include a fuel return line. Using the FMU in the back of the car, you stay much "closer" within the constructs of the stock fuel system, only adding the vacuum line to the back of the car. An "addition" as opposed to almost a complete alteration to the stock fuel system.
There's my guess. I think it's reasonable,but maybe just a bit more risky though. Vacuum lines are so much more touchy than are fuel lines.
