    TFS Package - Injectors?; pistons for rebuild

    John George's note about the discount for the package was timely - last year I bought the Mass Air, TB... and Injectors... from Summit. Ready for the rest!

    But the 2014 rules have the injectors crossed out. Did I miss something?

    Thanks,
    Eric

    PS- any source for pistons for a 30 over rebuild?

    Eric,

    At the bottom of page 14 in the Fuel System chapter is where you'll find what you're looking for.

    "11.4 Fuel Delivery System
    The factory fuel rail must be used. Any make or size of fuel injector may be used provided they fit in the unmodified fuel rail and intake manifold. The OEM fuel pressure regulator may be replaced with an adjustable fuel pressure regulator. Only one pressure regulator per car is allowed. Any adjustable regulator may be used that fits on the factory OEM mount and has a single screw adjustment and a vacuum port. There must be a stock type Schrader valve for testing fuel pressure. It must be installed in the high pressure side of the system."

    You don't have to run the TFS injectors anymore since folks were reporting that they were at or past the duty cycle, so some folks have moved to the 30lb red top Ford injectors this season. I have a set but still running the TFS injectors.
