Delphi FG1228 Fuel Pump Module Assembly

The Delphi FG1228 fuel pump module assembly is a standard replacement in-tank electric fuel pump for gas applications. Built from Delphi’s OE-focused engineering background, it combines the pump, fuel level sender assembly, strainer, gasket or seal, and quick-connect outlet design for service on select Mercedes-Benz ML-Class SUVs.

Key Features

• In-tank electric fuel pump module assembly for gas fuel systems
• 12-volt operation with a maximum pressure rating of 80.0
• Average flow rating of 31 and average current draw of 8
• Fuel level sender assembly included for accurate tank level reporting
• Strainer and gasket or seal included for service replacement
• Quick-connect outlet type with two outlets and blade terminals
• Standard replacement grade for direct-fit service work

Detailed Description

Delphi FG1228 is engineered as an in-tank fuel pump module assembly for Mercedes-Benz ML320, ML350, and ML500 applications. It is built for 12.0-volt gas systems and includes the fuel level sender assembly, internal strainer, and gasket or seal needed for a complete module replacement. The unit uses a quick-connect outlet design, male blade terminals, and a standard replacement configuration to match the original fuel delivery setup on the listed vehicles. Delphi draws on OE heritage and decades of supplier experience to support consistent fuel delivery and sender performance in service applications.

This part cross-references Airtex Fuel Pumps E8389M and Carter P76501M for the same application. Delphi FG1228 is also referenced in Mercedes-Benz fuel system catalogs under related OE and aftermarket numbers.

Vehicle Fitment

• Fits 2003-2005 Mercedes-Benz ML350, N/A
• Fits 2002-2005 Mercedes-Benz ML500, N/A
• Fits 2003 Mercedes-Benz ML320, N/A
• Fits 2002 Mercedes-Benz ML320, N/A

Common Replacement Uses

• Fuel pump failure causing hard starting or no-start conditions
• Weak fuel delivery under load or at higher engine demand
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel pressure loss related to an aging in-tank module
• Service replacement after tank contamination has affected the pump

Installation Notes and Tips

Before installing Delphi FG1228, clean the fuel tank thoroughly to reduce the risk of premature pump failure from contamination. For the 2002 Mercedes-Benz ML320, the fitment note specifies use from chassis # A289560 and recommends cleaning the tank before installation; use of fuel tank cleaning kit FC01 is recommended. Verify electrical connector style, outlet routing, and tank condition before reassembly.

Quality Assurance

Delphi builds this fuel pump module assembly using OE-based knowledge developed through long-term supplier experience with major automakers. The FG1228 is a standard replacement part intended to restore fuel delivery performance and sender function on the listed Mercedes-Benz ML-Class applications.
