Genuine GM LS1 Fuel Rail & 8 Injectors 12590212 12561462 - Used - VT VX VY VZ Commodore 5.7L

Genuine GM fuel rail assembly with all 8 injectors, removed from a running VZ Commodore 5.7L LS1. Rail part number 12590212, injectors 12561462. Complete assembly including crossover, regulator and mounting brackets.

The injectors are the good ones

12561462 is the 2001–2004 LS1/LS6 injector — around 30 lb/hr at 58 psi (Bosch 0280155931, EV1 connector). That's a genuine step up from the 27.3 lb/hr 12555894 injectors fitted to earlier VT and VX cars, and enough headroom for a cammed, headers-and-tune LS1 without going aftermarket. Popular as a straight upgrade for VT/VX owners and as a rebuild set for anyone with tired, leaking originals.
