Where can I find the fuel pump on a 2003 Infiniti G35?

To reach the fuel pump of a 2003 INFINITI G35, start by lifting the rear seats using the rings on each end of the second row. Once the seats pop out, slide the bottom seatbelt connectors through the holes, allowing you to remove the seats through the back doors. Under the passenger side's rear seat, you will find the fuel pump below a floor panel. The sending unit is located under the floorboards behind the driver's seat. The fuel pump is held in place by four tabs at each corner, which can be rotated clockwise to release. Signs of a failing fuel pump include difficulty starting, sputtering at high speeds, poor acceleration, reduced fuel efficiency, and frequent stalling. The typical cost for replacement on the INFINITI G35 ranges from $670 to $700 for parts and labor.
