Delphi FG2184 Fuel Pump Module Assembly

Fuel Pump Module Assembly for OE-Style Fuel Delivery

The Delphi FG2184 fuel pump module assembly is a standard replacement for select Cadillac, Buick, and other GM applications that use an in-tank electric fuel system. Built with Delphi OE heritage and application-specific engineering, it supports consistent fuel delivery, fuel level reporting, and vapor pressure sensing in flex-fuel vehicles.

Compatible with 2013-2019 Cadillac XTS, 2014-2017 Buick Regal, and 2012-2016 Buick LaCrosse, this module is built around the original system requirements for pressure, electrical connection, and tank-mounted operation.

• Fuel pressure regulator included
• Fuel level sender assembly included with float arm
• Strainer included with internal strainer design
• Quick-connect outlet with 0.375 in. outside diameter
• Blade terminals, 4-terminal male connection
• Gasket or seal included
• Supports flex-fuel applications
• Vapor pressure sensor included

Detailed Description

Delphi FG2184 is engineered as an OE-style replacement fuel pump module assembly for vehicles that require an in-tank electric pump, integrated sender, and vapor pressure sensor. Delphi draws on more than a century of OE experience, and that background is reflected in the module’s fit, electrical layout, and fuel system configuration. The assembly is designed for direct replacement use on 2013-2019 Cadillac XTS, 2014-2017 Buick Regal, and 2012-2016 Buick LaCrosse applications listed in the fitment data.

This module includes the fuel pump, regulator, strainer, gasket or seal, and fuel level sender assembly. It uses a quick-connect outlet, blade terminals, and a 12.0-volt electric pump design with an average current draw of 10 amps. The unit is specified for flex fuel systems and includes a vapor pressure sensor, making it a practical choice when replacing a worn or failing fuel pump module in GM vehicles that rely on integrated tank-mounted fuel delivery.

This part cross-references ACDelco (e.g., 13518163, 13578379) for the same application.

What It Helps Fix

• Hard starting caused by weak fuel pressure
• Engine stalling from inconsistent fuel delivery
• Fuel gauge errors from a failing sender assembly
• Fuel system warning lights related to vapor pressure sensing
• Driveability issues tied to a worn in-tank pump module

Installation Notes and Tips

Before installation, clean the fuel tank to help prevent future seal problems, as noted in the fitment data. Verify the vehicle’s fuel system configuration, electrical connector style, and outlet connection before replacement. Because this is an in-tank module assembly, proper tank access and careful sealing are important for reliable operation after installation.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through supplier experience with major automakers. FG2184 is a standard replacement fuel pump module assembly intended to match the original system requirements for the listed Cadillac and Buick applications.
