Product Details

Delphi FG1254 is engineered as an in-tank fuel pump module assembly for vehicles that require a gas fuel pump with integrated sender support. Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers, bringing that background into aftermarket replacement parts for a wide range of vehicles and model years. This part cross-references Bosch 69544 for the same application.

Fits 2003-2005 Hyundai Sonata, N/A. Fits 2003-2004 Kia Optima, N/A. Fits 2002 Hyundai Sonata, N/A.

Common Replacement Reasons

• Hard starting or extended cranking from low fuel pressure
• Engine stalling caused by inconsistent fuel delivery
• Incorrect fuel gauge readings from a worn sender assembly
• Fuel pump noise or loss of pump output in the tank
• Fuel delivery issues after tank contamination or debris buildup

Installation Notes and Tips

Before installing Delphi FG1254, clean the fuel tank to reduce the chance of debris damaging the replacement pump or affecting the seal. Delphi notes tank contamination as a leading cause of premature fuel pump failure, and recommends cleaning the tank before service; for the 2002 Hyundai Sonata, use of fuel tank cleaning kit FC01 is recommended. Verify electrical connector style, hose routing, and system pressure requirements before installation.

Quality Assurance

Delphi builds this fuel pump module assembly using OE-focused engineering knowledge and application coverage developed through long-term supplier experience. The FG1254 is a standard replacement part for select Hyundai Sonata and Kia Optima applications, with components selected to support reliable fuel delivery and sender operation.
