• In-tank electric fuel pump module assembly for gasoline systems
• Includes fuel level sender assembly and float arm
• Vapor pressure sensor included
• Quick-connect outlet for service-friendly connection
• Blade terminals with 9-terminal male configuration
• Internal strainer included
• 12-volt operation with standard replacement construction
• Delphi FG2459 is backed by OE heritage and application knowledge

Product Details

Delphi FG2459 is engineered as a standard replacement fuel pump module assembly for vehicles that require an in-tank electric pump with integrated level sensing. Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers, then applies that background to aftermarket fuel system components. This part number is a direct-fit option for 2017-2021 Hyundai Ioniq and 2017-2021 Kia Niro applications listed below, making it a practical choice for fuel system service on these platforms. This part cross-references a single alternate number for the same application: CFG2459.

Vehicle Fitment

• Fits 2017-2021 Hyundai Ioniq, N/A. Clean fuel tank before installing fuel pump to prevent future seal problems.
• Fits 2017-2020 Kia Niro, N/A. Clean fuel tank before installing fuel pump to prevent future seal problems.
• Fits 2021 Kia Niro, N/A.

What It Helps Fix

• Hard starting caused by weak or failing fuel delivery
• Engine hesitation or stalling from inconsistent pump output
• Incorrect fuel level readings from a worn sender assembly
• Fuel system faults related to the vapor pressure sensor
• Noise or performance issues from an aging in-tank pump module

Installation Notes

Confirm the tank is clean before installation, especially on Hyundai Ioniq and Kia Niro applications, to reduce the risk of future seal problems. Verify the outlet style, terminal layout, and in-tank configuration against the original unit before service. Because this assembly includes a fuel level sender and vapor pressure sensor, inspect related connectors and wiring during replacement.

Quality Assurance

Delphi builds this fuel pump module assembly using OE-based engineering knowledge developed through long-term supplier experience with major automakers. FG2459 is designed as a standard replacement part for the listed Hyundai and Kia applications and is supported by Delphi’s broad aftermarket fuel system portfolio.
