Deliver the high-pressure fuel a direct-injection V8 demands with the Hitachi Astemo Direct Injection High Pressure Fuel Pump (HPP0026), a NEW actual OE part. It's a direct-fit replacement for the 5.6L (V8-5.6L) engine in the 2011-2013 INFINITI M56, 2014-2019 INFINITI Q70, 2011-2013 INFINITI QX56, 2014-2021 INFINITI QX80, 2017-2021 NISSAN TITAN and ARMADA, and more — see the Buyer's Guide tab for the full application list. A mechanically driven high-pressure pump steps fuel pressure up from the low-pressure supply so the direct injectors can spray fuel straight into the combustion chambers; if a worn or failing pump is behind hard starting, rough running, a loss of power, or a fuel-pressure code, this replaces it.
- NEW OE part: a genuine Hitachi high-pressure fuel pump, not a rebuilt unit.
- Mechanical operation: mechanically actuated high-pressure pump.
- External mounting: mounts externally (not an in-tank unit).
- Male terminal: connects through a male terminal.
Please note: no gasket or seal, fuel sending unit, or tank seal is included — consult the vehicle service information for the correct seals and hardware. Country of origin: Japan.
