GT-R Fuel Pump Number: 17040-JF30C, 17040-89S0A, 17040-JF30A, 17040-JF30B.

Now that doesn't necessarily mean it will not fit, I am just not sure if it will. If you are replacing the pump I would just contact CJ Motorsports and obtain one of their fuel pumps. Better flow than OEM for both 370z & GT-R.
