Detailed Description

This Delphi fuel pump module assembly is engineered for diesel fuel systems and built to support consistent fuel delivery in select Mercedes-Benz GL320, ML320, GL350, and ML350 models. The FG2173 includes the pump module assembly with float arm and an instruction sheet, along with an internal strainer and fuel level sender assembly to address both fuel supply and tank level feedback in one service component. Delphi’s OE heritage and supplier experience are reflected in the design and application coverage for these Mercedes-Benz diesel platforms.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons to Replace

• Hard starting or no-start conditions caused by weak fuel delivery
• Fuel pressure loss in the in-tank diesel supply system
• Erratic or inaccurate fuel gauge readings from a worn sender
• Noise or inconsistent operation from an aging electric pump
• Restricted fuel flow related to a contaminated internal strainer

Installation Notes and Tips

Before installing the fuel pump module, clean the fuel tank to help prevent future seal problems, especially on Mercedes-Benz GL320, ML320, GL350, and ML350 diesel applications. Verify right-side placement, outlet style, terminal configuration, and electrical connection before installation. Inspect the tank opening and sealing surfaces carefully, and confirm the fuel system is free of contamination before returning the vehicle to service.

Quality Assurance

Delphi builds aftermarket parts using OE experience and application knowledge developed through long-term supplier relationships with major automakers. FG2173 is a standard replacement fuel pump module assembly intended to match the needs of the listed Mercedes-Benz diesel fitments with the correct in-tank configuration and sender integration.
