Delphi FG0491 Fuel Pump Module Assembly

Delphi FG0491 Fuel Pump Module Assembly

Delphi FG0491 is an in-tank electric fuel pump module assembly for gas applications, built with OE heritage and application knowledge drawn from Delphi’s long history supplying automakers. It includes the fuel level sender assembly, regulator, strainer, gasket or seal, and a quick-connect outlet design for service on select Buick, Chevrolet, and Pontiac vehicles.

Key Features

• In-tank electric fuel pump module assembly for 12-volt gas systems
• Maximum pressure rating of 80.0 and system pressure of 58 psi
• Fuel level sender assembly included with resistance range of 250 ohms empty and 40 ohms full
• Regulator included for integrated fuel delivery control
• Strainer and gasket or seal included for replacement service
• Quick-connect outlet with two outlets and 0.375 in. outlet outside diameter
• Standard replacement grade for direct service use

Detailed Description

This Delphi FG0491 fuel pump module assembly is built for select 2007-2008 Buick Allure, 2007-2008 Buick LaCrosse, 2007-2008 Chevrolet Impala, 2007 Chevrolet Monte Carlo, and 2008 Pontiac Grand Prix applications with California Emission System, Partial Zero Emissions Vehicle requirements, and RPO Code NU6 where noted. It is also listed for 2008 Buick LaCrosse and 2008 Pontiac Grand Prix with Delphi fuel system coverage. Delphi’s OE-focused engineering is reflected in the integrated pump, sender, regulator, and strainer layout, helping restore fuel delivery and fuel level reporting in one service part. This part cross-references Airtex E3824M and Carter P76238M for the same application.

What It Helps Fix

• Hard starting caused by weak or inconsistent fuel delivery
• Engine stalling from low fuel pressure
• Fuel gauge readings that are inaccurate or intermittent
• Fuel starvation under load or during acceleration
• Noise or wear associated with an aging in-tank pump module

Installation Notes and Tips

Confirm vehicle emission package, RPO code, and fuel system configuration before ordering. For listed Buick, Chevrolet, and Pontiac applications, Delphi recommends cleaning the fuel tank before installing a new pump to reduce the risk of contamination-related failure; fuel tank cleaning kit FC01 is recommended. Verify quick-connect line fitment, terminal style, and sender resistance specifications during installation.

Quality Assurance

Delphi builds this module using OE experience and heritage developed through decades of supplying major automakers. The FG0491 is a standard replacement fuel pump module assembly intended to meet the needs of the specified vehicle applications with integrated components for fuel delivery and level sensing.
