Detailed Description

Delphi FE0688 is an in-tank electric fuel pump designed for fuel delivery systems that require a gasoline-compatible, 12V replacement unit. It uses pin-style, male terminals with a two-terminal layout and is configured for in-tank mounting. The pump does not include a gasket or seal, wiring harness, or strainer, so verify all related service parts before installation.

Compatible With 2014-2017 Hyundai Azera, In-Tank, and 2014-2016 Kia Cadenza, In-Tank. This part cross-references Monroe Shocks & Struts (e.g., CFE0688) for the same application. If you are servicing a Hyundai Azera or Kia Cadenza fuel system, FE0688 provides the correct in-tank replacement format for the listed vehicles.

What This Fuel Pump Helps Address

  • Hard starting caused by weak fuel delivery
  • Engine hesitation under load from low fuel pressure
  • Stalling related to inconsistent pump output
  • Fuel starvation symptoms during acceleration
  • Poor drivability from a failing in-tank pump

Installation Notes and Tips

Install FE0688 only in the confirmed in-tank locations listed above. Delphi notes that the fuel tank should be cleaned before installing the fuel pump to help prevent future seal problems. Because the gasket or seal is not included, inspect the tank opening, electrical connector, and fuel lines before reassembly. Confirm terminal type, outlet size, and system pressure requirements before installation on a Hyundai Azera or Kia Cadenza.

Quality Assurance

Delphi draws on more than 100 years of OE experience and a broad aftermarket portfolio built from supplier knowledge used by major automakers. FE0688 reflects that OE-based engineering approach for standard replacement fuel system service.
