Detailed Description

Delphi FG1253 fuel pump module assembly is a standard replacement part engineered for select 2004-2005 Kia Rio applications. Delphi draws on OE experience and supplier knowledge developed across decades of original-equipment service, and that background is reflected in the module’s integrated design, which combines the pump, sender, regulator, strainer, and sealing components in one in-tank assembly. For shoppers searching for a 2004 Kia Rio fuel pump module assembly or a 2005 Kia Rio fuel pump module assembly, FG1253 provides the core components needed for fuel delivery and fuel level signal output in one service part.

This part cross-references Delphi CFG1253 for the same application.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel delivery
• Engine stalling related to low fuel pressure
• Fuel gauge readings that are inaccurate or intermittent
• Fuel system issues tied to a worn pump module or sender
• Sealing concerns after fuel tank service when the gasket or seal is replaced

Installation Notes and Tips

Fits 2004 Kia Rio, N/A. Fits 2005 Kia Rio, N/A. For the 2004 Kia Rio, the fitment note specifies fuel tank contamination as a leading cause of premature pump failure; cleaning the tank before installation is recommended, and use of fuel tank cleaning kit FC01 is noted. For the 2005 Kia Rio, the fitment note also advises cleaning the fuel tank before installing the fuel pump to help prevent future seal problems. Verify connector style, outlet type, and tank condition before installation.
