In the R/T I just got the fuel rails cross at the back of the engine. The fuel comes in drivers side to "T" fitting before the fuel rail which sends it to passenger side "T" before fuel rail and e fuel line to regulator all 8an fittings. Has anyone used or seen this kind of setup before on a return system setup, I haven't seen it set up like this before. I did my R/T with cross in front of fuel rails and found a short plug for A/C. Just trying to get the beast running.
