Detailed Description

Delphi FG1731 is an in-tank electric fuel pump module assembly engineered as a standard replacement for vehicles that use a module-style fuel delivery system. It includes the pump, float arm, fuel level sender assembly, regulator, strainer, and seal, helping restore fuel delivery and tank-level signal performance in one service part. This part cross-references Spectra Premium SP6682M for the same application. Fits 2009-2011 Buick Lucerne, N/A.

Delphi draws on OE heritage and supplier experience with major automakers, and that background is reflected in the FG1731’s application-focused design and component integration. The module uses a quick-connect outlet, blade terminals, and an internal strainer layout suited to direct replacement service on supported vehicles. Delphi FG1731 is also referenced by part number 19179798.

What It Is Used For

• Restoring fuel pressure when the original pump is worn or weak
• Correcting inaccurate fuel level readings from a failing sender
• Replacing a noisy or inconsistent in-tank fuel pump module
• Addressing hard-start, stall, or fuel starvation symptoms tied to pump output
• Servicing a leaking module seal or degraded strainer assembly

Installation Notes and Tips

Before installation, clean the fuel tank to help prevent future seal problems, especially on 2009-2011 Buick Lucerne applications. Verify connector style, outlet type, and system pressure requirements before installation. Confirm the tank is properly relieved of fuel pressure and follow vehicle service procedures for in-tank module replacement.

Quality Assurance

Delphi builds this fuel pump module assembly using OE-based engineering knowledge and a broad aftermarket coverage strategy for a wide range of vehicles and model years. The FG1731 is a standard replacement part intended to meet the needs of the listed application.
