Delphi FG0078 Fuel Pump Module Assembly

Delphi FG0078 Fuel Pump Module Assembly

Delphi FG0078 is an in-tank fuel pump module assembly for gasoline applications, built for direct replacement service on select 1997 Buick Century and 1997 Buick Regal models. It combines the pump, fuel level sender assembly, vapor pressure sensor, and sealing components in one OE-style service part.

Key Features

• In-tank electric fuel pump module assembly for gas fuel systems
• Maximum pressure rating of 109.0 and system pressure of 52 psi
• Fuel level sender assembly included with 40.0 ohms empty and 250.0 ohms full resistance
• Vapor pressure sensor included
• Quick-connect outlet design with 3 outlets and 0.375 in. outlet outside diameter
• Strainer and gasket/seal included for service replacement
• 13.0-volt operation with 7 amp average current draw and 17 average flow rating
• Standard replacement grade from Delphi, part number FG0078

Detailed Description

Delphi FG0078 is engineered as a standard replacement fuel pump module assembly for 1997 Buick Century and 1997 Buick Regal applications. Delphi draws on OE experience and supplier knowledge from its work with major automakers, and that background is reflected in the module’s integrated design, which includes the pump, sender, strainer, seal, and harness-related service components listed in the package contents. The assembly uses a pin-style, 4-terminal male connection, an internal strainer, and an in-tank electric pump layout for gasoline fuel delivery. If you are replacing a worn fuel pump module on a 1997 Buick Century or 1997 Buick Regal, Delphi FG0078 provides the core components needed for a direct service repair.

This part cross-references Carter P74792M and Spectra Premium SP3980M for the same application.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent pump output
• Fuel gauge errors related to a failing sender assembly
• Fuel pressure loss in the tank-mounted delivery system
• Vapor pressure sensor faults tied to the module assembly

Installation Notes and Tips

Before installing Delphi FG0078, clean the fuel tank to reduce the risk of seal contamination and future sealing problems. Verify the electrical connector, outlet style, and in-tank configuration before removal, and confirm the vehicle is a 1997 Buick Century or 1997 Buick Regal. Inspect the tank opening and sealing surface carefully so the included gasket or seal seats correctly during reassembly.

Quality Assurance

Delphi builds this fuel pump module with OE heritage and application knowledge developed through long-term supplier experience with major automakers. The FG0078 is a standard replacement part designed to meet the service needs of the listed Buick applications using the specified fuel system configuration.
