Delphi FG1231 Fuel Pump Module Assembly

Delphi FG1231 Fuel Pump Module Assembly

The Delphi FG1231 fuel pump module assembly is a standard replacement for in-tank gasoline fuel systems. Built with Delphi’s OE heritage and application knowledge, it supports consistent fuel delivery, integrated fuel level sensing, and regulated system pressure for the vehicle’s original setup.

Compatible with 2001-2002 Kia Rio fuel system applications, this module is built for direct replacement service where the original pump assembly has failed or fuel delivery has become inconsistent. The FG1231 is also a fitment-based search match for 2001 Kia Rio fuel pump module assembly and 2002 Kia Rio in-tank fuel pump replacement.

Key Features

• In-tank electric fuel pump module assembly for gasoline applications
• Includes fuel pressure regulator and vapor pressure sensor
• Fuel level sender assembly included for tank level reporting
• Quick-connect outlet design with two outlets
• Internal strainer and gasket or seal included
• 12-volt electrical system with blade terminals
• Maximum pressure rating of 80.0 and system pressure of 44 psi
• Standard replacement part built for OE-style service

Detailed Description

Delphi FG1231 is a fuel pump module assembly engineered for in-tank installation on gasoline vehicles. It includes the pump, float arm, fuel level sender assembly, regulator, strainer, and seal components needed to restore fuel delivery and tank level feedback in the original system. The module uses a 12.0-volt electric pump with a blade terminal connection, quick-connect outlets, and a 0.375-inch outlet outside diameter.

For 2001-2002 Kia Rio applications, this Delphi FG1231 assembly supports direct replacement of the original in-tank fuel pump module. Delphi’s OE background is reflected in the part’s design approach, with attention to fuel pressure control, sender resistance range, and vapor pressure sensing for the vehicle’s fuel system layout. This part cross-references Airtex Fuel Pumps (e.g., E8420M) for the same application.

What This Part Helps Address

• Hard starting caused by weak or failing fuel delivery
• Engine stalling from inconsistent fuel pressure
• Fuel gauge readings that no longer track tank level correctly
• Fuel pump noise or loss of pump operation
• Fuel system pressure issues in an in-tank gasoline setup

Installation Notes and Tips

Fits 2001-2002 Kia Rio, N/A. Clean the fuel tank before installing the fuel pump to prevent future seal problems. Verify electrical connector style, outlet routing, and tank condition before installation. Because this is an in-tank module assembly, proper sealing and clean tank surfaces are important for reliable operation.

Quality Assurance

Delphi builds this replacement fuel pump module using OE experience and supplier knowledge developed across a wide range of vehicle applications. The FG1231 is a standard replacement part intended to restore original fuel system function with OE-style component integration.
