Direct Injection Fuel Pump Overview

Standard Ignition GDP733 is a direct injection high pressure fuel pump for gasoline direct injection systems. It is built with a mechanical design, an oval connector shape, and a 2-blade terminal layout for a direct-fit replacement in supported applications.

Compatible With Nissan Pathfinder and INFINITI QX60 applications, this fuel pump is intended for direct fuel system service where precise high-pressure delivery is required. The GDP733 part number is also referenced as GDP733 for identification during ordering and service lookup.

Key Features

• Mechanical high pressure fuel pump for gasoline direct injection systems.
• Oval connector shape with 2 blade terminals.
• Submersible design for fuel system use.
• Bolts included for installation.
• Standard Ignition GDP733 identification for catalog matching.

Detailed Description

Standard Ignition GDP733 is a direct injection high pressure fuel pump engineered for gasoline direct injection fuel systems. The mechanical construction, direct system type, and oval electrical connector support service replacement in vehicles that use this style of fuel delivery. Fitment includes 2017-2024 Nissan Pathfinder and 2017-2020 INFINITI QX60, with a 2022 INFINITI QX60 application also listed separately in the fitment data.

This part cross-references 2-34273 and 800-6337 for the same application. Use GDP733 when replacing a failed high pressure pump in a Nissan Pathfinder or INFINITI QX60 equipped with GDI fuel delivery. The GDP733 part number should be matched carefully to the vehicle’s fuel system configuration before installation.

What It Is Used For

• Hard starting caused by insufficient high-pressure fuel delivery.
• Fuel pressure loss in a gasoline direct injection system.
• Engine hesitation or stumble under load.
• Driveability issues related to pump wear or internal leakage.
• Fuel system service on supported Nissan Pathfinder and INFINITI QX60 models.

Installation Notes and Tips

Confirm the vehicle uses a direct injection high pressure fuel pump with an oval connector and 2 blade terminals before ordering. Verify the fuel system layout and compare the original part number, including GDP733, against the existing unit. Bolts are listed as included; wiring harness, gasket, filter, and strainer are not included.

Quality Assurance

Standard Ignition supplies this fuel pump as a cataloged replacement part for direct injection fuel system service. Match the application carefully to the vehicle’s fuel delivery configuration and part number before installation.
