Victor Jr Rail Setup I'm considering getting a Vic Jr to go with my build but I have a small question about the fuel rails setup. I have an -8an line to the engine with the in-line pump, filters and regulator in the trunk. The return is in the trunk with the regulator (mostly didn't want to run a secondary line).
On the rails, how should I setup the fuel lines. Connect the rails at the front together and have the rear split off with a Y fitting to each rail? Or run the line to one rail and plug the other? Or, do I need a return line from the rails?

Buy my setup and most of the plumbing is already there for you.

I was using an in-tank pump that regulated pressure at the pump. If you are regulating in the trunk, then you should only need one line to the front. I entered on the driver side, crossed in the front, and plugged the passenger side. I had 2 pressure gauges on the lines, one on both sides. I never saw much of a difference in pressure between the 2. I only run -6 to the front, but the rails are -8 as it my crossover...

In theory there will be high pressure at the rear by they current setup than up at the rail in the front of the car, so you should be able to take the current setup and add a tiny return line from the front with a second regulator set to just less than half a pound lower than the rear and it would only have to return a small amount and only need a small line that would be easier to run. Just thinking out loud.
