Detailed Description

Delphi FG1258 is engineered as an OE-style fuel pump module assembly for select 2003-2006 Hyundai Santa Fe vehicles. Delphi draws on long-standing OE supply experience, and that background is reflected in the module’s fitment-focused design, electrical configuration, and fuel delivery specifications. The unit is built for in-tank installation, uses an external strainer, and supports gasoline fuel systems with an average flow rating of 40 and average current draw of 8.

This fuel pump module assembly is a practical choice when replacing a worn pump, sender, or module on a Hyundai Santa Fe. The included fuel level sender assembly helps restore fuel gauge operation, while the quick-connect outlet and blade terminals support straightforward integration with the vehicle’s fuel system layout. Delphi FG1258 is also referenced by multiple aftermarket and OE-style part numbers, including Beck/Arnley 152-0998 and Carter P76405M.

Common Problems This Part Can Address

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent fuel pressure
• Fuel gauge readings that no longer match tank level
• Low fuel pressure in an in-tank gasoline system
• Noise or wear associated with an aging fuel pump module

Installation Notes and Tips

Before installing a replacement fuel pump module assembly on a 2003-2006 Hyundai Santa Fe, clean the fuel tank to reduce the risk of contamination-related seal problems and premature pump failure. For 2003 Hyundai Santa Fe applications from 01/15/2003, tank cleaning is especially important; Delphi recommends using fuel tank cleaning kit FC01. Confirm the electrical connector, outlet style, and sender resistance requirements before installation.
