My set up is very similar to Mando, I have factory commodore tank fitted with a factory V8 (VN I think) lift pump, this feeds to the back of the L/H rear guard where I have a factory VT fuel pump in a swirl pot (supplied by Aussie Mike). The lift pump supplies fuel to the swirl pot, the main pump is connected just as it would be in a VT commodore (even has all the factory hoses with push on connections), So like the commodore it only runs a single line to the front of the car (although when building my car I did install a return line for use later when a larger motor is fitted).
And with the factory hoses at the back and VT pump as main feed, this is all built with inbuilt regulator and inbuilt return line that feeds back into the swirl pot.
