Detailed Description

Built by Delphi, a Tier 1 supplier with long-standing fuel system manufacturing experience, the FG2684 fuel pump module assembly is engineered for direct replacement service on the Mazda CX-9. Delphi’s fuel delivery background includes OE-focused development and broad North American market coverage, making this module a practical choice for restoring fuel delivery performance and fuel level reporting in one service event. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with 2016-2023 Mazda CX-9, this Delphi FG2684 assembly is designed for in-tank installation and uses a quick-connect outlet with a 0.375-inch outside diameter. The module includes the float arm, seal, instruction sheet, internal strainer, and fuel filter, helping streamline replacement of a worn or failing pump module on the Mazda CX-9.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Engine hesitation or stalling from inconsistent pump output
• Incorrect fuel gauge readings from a failing sending unit
• Low fuel pressure conditions in gas-powered systems
• Fuel starvation from a clogged or worn in-tank module

Installation Notes and Tips

Install this module in the fuel tank only, following the vehicle service procedure for the 2016-2023 Mazda CX-9. Verify connector shape, terminal count, outlet style, and seal condition before installation. Replace the tank seal during service and confirm proper electrical connection, fuel line engagement, and fuel pressure after installation. The package includes an instruction sheet for reference.
