Detailed Description

Delphi FG1246 is engineered for select Mazda 6 vehicles and is built around OE heritage and application knowledge developed through long-term supplier experience with major automakers. This fuel pump module assembly is designed for in-tank installation and includes the pump, regulator, strainer, and fuel level sender assembly to restore fuel delivery and tank level signaling in one service part. The unit uses a quick-connect outlet, male blade terminals, and a 12.0-volt electric pump design for gasoline fuel systems. Delphi FG1246 also cross-references Airtex E8588M and Carter P76311M for the same application.

Common Problems It Can Address

• Hard starting caused by weak or inconsistent fuel pressure
• Engine stalling from insufficient fuel delivery
• Fuel gauge inaccuracies from a worn sender assembly
• Loss of pressure in the fuel system under load
• Poor drivability related to a failing in-tank pump module

Installation Notes and Tips

Before installing a replacement pump module in a Mazda 6, clean the fuel tank to reduce the risk of contamination damaging the new unit. Delphi recommends using fuel tank cleaning kit FC01. Verify the vehicle’s emission configuration and model year before installation, and confirm the electrical connector and quick-connect outlet match the original setup. The package includes the fuel pump module assembly with float arm, seal, and instruction sheet.
