Delphi FG1143 is an in-tank fuel pump module assembly for gas applications, built with OE heritage and application-specific engineering. It includes the fuel level sender assembly, regulator, strainer, gasket or seal, and a quick-connect outlet for a direct replacement on select Ford, Lincoln, Mazda, and Mercury vehicles.

Key Features

• In-tank electric fuel pump module assembly for gas fuel systems
• 12V design with a maximum pressure rating of 68.0 and system pressure of 65 psi
• Fuel level sender assembly included for accurate tank level reporting
• Regulator included for integrated fuel delivery control
• Strainer and gasket or seal included for service-ready installation
• Quick-connect outlet with 0.375 in. outside diameter
• Male pin terminals, 4-terminal configuration
• Standard replacement grade for select OE-style applications

Detailed Description

Delphi FG1143 is engineered as a standard replacement fuel pump module assembly for vehicles that use an in-tank electric pump with an integrated sender and regulator. Delphi draws on more than 100 years of OE experience, and that OE knowledge is reflected in the module’s fit, function, and component layout. This part number is used in applications such as the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ, 2009-2010 Mazda 6, 2006-2009 Mercury Milan, and 2006 Lincoln Zephyr. Delphi FG1143 also cross-references Spectra Premium SP1381 for the same application.

What It Helps Fix

• Hard starting caused by weak or failing fuel pressure
• Engine stalling from inconsistent fuel delivery
• Incorrect fuel gauge readings from a worn sender assembly
• Fuel starvation under load from a restricted or failing pump module
• Fuel system leaks related to a deteriorated seal or module interface

Installation Notes and Tips

Before installing this fuel pump module assembly, clean the fuel tank to reduce the risk of future seal problems. Verify the vehicle’s fuel system uses an in-tank, 12V gas pump module with a quick-connect outlet and 4-pin male terminal layout. Confirm fitment by year, make, and model before service, especially on Ford Fusion, Lincoln MKZ, Mazda 6, Mercury Milan, and Lincoln Zephyr applications.

Quality Assurance

Delphi builds this module using OE-based engineering and a broad aftermarket portfolio developed from supplier experience with major automakers. FG1143 is specified as a standard replacement fuel pump module assembly for the listed applications.
