Restore high-pressure fuel delivery to your direct-injection Hyundai V8 with the Standard Ignition Direct Injection High Pressure Fuel Pump (GDP407). It's a direct-fit OE replacement for the 2011 Hyundai Equus [V8-4.6L], 2012 Hyundai Equus [V8-5.0L], 2009-2012 Hyundai Genesis [V8-4.6L] and 2012 Hyundai Genesis [V8-5.0L]. This mechanical pump raises the fuel to the high pressure the GDI (direct injection) system's injectors require. If a worn or failing high-pressure pump is the cause of hard starts, long cranking, rough running, or low fuel-rail-pressure codes, this replaces it.
