Thread: SysteMax Intake Fuel Rails

  1. #1

    Default SysteMax Intake Fuel Rails

    Just wondering what fuel rails will work with the SysteMax II intake manifold. Stock Mustang 5.0L style Holley fuel injectors, EV1, I believe.

    I'm pretty sure the SysteMax 2 is designed to use the stock fuel rail. Andrew

    Yes, I have a Thunderbird rectangular rail on now. I'm upgrading the fuel system. Holley drop-in pump, -8 feed & -6 return. I'll be installing a turbo to make around 1000 HP. Can't find a set of rails other than BBK, wanted to use a separate fuel pressure regulator.

    The instructions clearly illustrate the OEM fox Mustang fuel rails & injectors being reinstalled: (Holley SysteMax 2 Installation Instruction)

    I have the SysteMax II on my 347. I'm using the stock Mustang fuel rails with no issues. -Shannon
