Detailed Description

Delphi FG2666 is built for direct replacement service on select Hyundai luxury sedan applications, including the 2012-2014 Hyundai Equus and 2012-2014 Hyundai Genesis. As an in-tank fuel pump module assembly, it combines the pump, sender, regulator, and filtration components needed to restore fuel delivery and fuel level reporting in one service part. Delphi’s fuel system background includes decades of OE-focused manufacturing and fuel technology development, which is reflected in the design and component integration of this module. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel starvation under load or at higher demand
• Inaccurate fuel gauge readings from a worn sending unit
• Low fuel pressure from an aging in-tank pump assembly
• Driveability issues tied to restricted internal filtration

Installation Notes and Tips

Verify the vehicle application before installation, especially on 2012-2014 Hyundai Equus and 2012-2014 Hyundai Genesis models. This module uses a specific-fit configuration with a quick-connect outlet and female connector, so confirm connector shape, terminal count, and outlet layout against the original unit. The assembly includes a gasket/seal and float arm, but mounting hardware and lock ring are not included. Clean the tank area before removal, inspect the tank opening and electrical connector, and follow the instruction sheet during reassembly.
