Planning Fuel System

[Fuelie Fan]

I think what he is referring to is fuel rail harmonics. It's why returnless systems still have to run dampers in the fuel rail (that thing that looks like a regulator, but isn't)



What you described should be fine. It could be improved with a second crossover, but probably not necessary. Also, I tend to agree that it's cleaner if the lines are run along the same path, not on opposite sides of the car, but that's personal preference.
