Detailed Description

Delphi FG0385 fuel pump module assembly is a standard replacement part engineered for in-tank installation on gasoline vehicles. It is listed for 2004 Buick Rendezvous, 2005 Buick Rendezvous, 2004 Pontiac Aztek, and 2005 Pontiac Aztek, including the 2nd design applications noted in the fitment data. Delphi’s OE background and broad aftermarket coverage are reflected in the module’s sender, vapor pressure sensor, quick-connect outlet, and sealed in-tank construction.

This part cross-references Carter P76085M for the same application. The FG0385 part number is also referenced in interchange listings for related OE-style replacement use.

What It Is Used For

• Restoring fuel delivery when the original pump no longer maintains pressure
• Replacing a faulty fuel level sender that causes inaccurate gauge readings
• Addressing hard-start or no-start conditions tied to low fuel pressure
• Correcting drivability issues caused by inconsistent pump output
• Replacing a worn in-tank module on Buick Rendezvous and Pontiac Aztek models

Installation Notes and Tips

Clean the fuel tank before installing the replacement pump to reduce the risk of seal problems and premature failure. For the 2004 Buick Rendezvous and 2004 Pontiac Aztek applications, Delphi notes that fuel tank contamination is a leading cause of early pump failure and recommends using fuel tank cleaning kit FC01. Verify connector style, outlet type, and sender specifications before installation.

Quality Assurance

Delphi builds this module using OE experience and application knowledge developed through work with major automakers. FG0385 is a standard replacement fuel pump module assembly intended to meet the requirements of the listed Buick Rendezvous and Pontiac Aztek applications.
