Fore Innovations billet fuel rails for the LS7. Machined from a solid block of 6061 aluminum. Integrated mounting tabs eliminate rail tab flex under the highest intake and fuel pressures. Proper clearances and diagonally slotted mounting holes ensure proper injector alignment with OE length injectors or taller injectors.

Can be used with OE length injectors and/or alternate length injectors, select appropriate hardware pack for actual intake and injector combination
Must be used without coil pack covers or engine covers.
Use LS3 Rails (45-100) for Fast LSXr 102mm LS7 intakes
Fits MSD Atomic Airforce LS7 intake with Hardware Pack J. (uses OE length injectors only)
