Standard Ignition GDP759 Direct Injection High Pressure Fuel Pump

Direct Injection Fuel Delivery for Subaru Applications

Standard Ignition GDP759 is a direct injection high pressure fuel pump for gasoline applications. It is built for Subaru vehicles that require precise high-pressure fuel delivery to support direct injection operation and consistent engine performance.

Compatible With 2019-2022 Subaru Ascent, 2020-2023 Subaru Legacy, 2020-2023 Subaru Outback, and 2022 Subaru WRX.

Key Features

• Direct injection high pressure fuel pump for gasoline fuel systems
• Fuel delivery type: gas
• Gaskets not included
• Hardware not included
• Standard Ignition GDP759 replacement part number

Detailed Product Overview

This fuel pump is used in direct injection systems where fuel must be delivered at elevated pressure for proper atomization and combustion control. Standard Ignition GDP759 is a fitment-based replacement for select Subaru models, including the Subaru Legacy, Subaru Outback, Subaru Ascent, and Subaru WRX. This part cross-references 2-34298 and 16625AA110 for the same application.

Use GDP759 when replacing a worn or failing high pressure fuel pump on gasoline direct injection engines. The part number GDP759 is also a useful reference when verifying the correct fuel pump for Subaru Legacy and Subaru Outback service work.

What This Part Helps Address

• Hard starting caused by insufficient high-pressure fuel delivery
• Rough idle related to unstable fuel pressure
• Loss of power under load from fuel starvation
• Fuel pressure-related diagnostic trouble codes
• Driveability issues tied to direct injection pump wear

Installation Notes and Tips

Confirm engine code and VIN fitment before installation. Replace any required seals or gaskets separately, since gaskets are not included. Inspect the fuel system for contamination, pressure loss, or related component wear before installing the new pump. Follow factory service procedures for depressurizing the system and priming after installation.

Quality Assurance

Standard Ignition supplies replacement fuel system components for service applications. GDP759 is built to match the specified direct injection fuel pump application for the listed Subaru vehicles.
