    Fuel system question

    I am completely redoing the fuel system in my car and updating everything to 6an lines. I am doing a full wire tuck as well so I want to keep the engine bay as clean as possible.

    My question is how to setup the remove fuel pressure regulator on the car, a return or deadhead setup?

    what are the benefits/drawbacks of each one? I am leaning towards a dead head as that will keep things cleaner and only have one fuel line going to the engine.

    Here is a photo of what I am working with.

    I think the top diagram will insure the same pressure at all injectors. On a boosted application, it is important to not have a lean cylinder to avoid grenading the piston. Maybe someone has done some testing on this topic on youtube?
