Detailed Description
Delphi FG0863 fuel pump module assembly is engineered for direct replacement in the fuel tank on select Ford Explorer and Mercury Mountaineer models. It uses an electric pump with an average flow rating of 40 and an average current draw of 10, supporting consistent fuel delivery for the vehicle’s fuel system. The assembly includes the fuel level sender, external strainer, regulator, and seal, helping restore proper fuel supply and tank-level reporting in one service part. Delphi’s OE background and broad aftermarket coverage are built into this module for applications that require a standard replacement fuel pump assembly.
This part cross-references DENSO Auto Parts 950-0171 for the same application.
What It Helps Fix
- Hard starting caused by weak or failing fuel delivery
- Engine stalling from inconsistent fuel pressure
- Incorrect fuel gauge readings from a worn sender
- Fuel starvation under load in flex-fuel applications
- Noise or performance loss from an aging in-tank pump module
