OE-Style Fuel Delivery Construction

Delphi HP10128 is engineered from OE heritage and decades of supplier experience, with aftermarket coverage built around the needs of older Ford and Mercury fuel systems. It is a direct-fit fuel pump hanger assembly for 1997-1998 Ford Explorer and 1997-1998 Mercury Mountaineer models, and it also cross-references Delphi DHP10128 for the same application. The assembly includes the fuel pump hanger, float arm, sender, and service components needed to restore fuel delivery and fuel level signal performance in one repair.

Common Issues This Part Helps Address

• Hard starting caused by weak fuel pressure
• Engine hesitation or stalling from inconsistent fuel delivery
• Inaccurate fuel gauge readings from a worn sender
• Fuel starvation from a restricted or failing in-tank pump assembly
• Leak concerns related to aged seals or hanger components

Installation Notes and Tips

Compatible with 1997-1998 Ford Explorer and 1997-1998 Mercury Mountaineer fuel tank applications. For Ford Explorer models, Delphi recommends cleaning the fuel tank before installation to reduce the risk of seal problems and premature pump failure; tank contamination is a common cause of repeat fuel system issues. Inspect the tank, electrical connector, and fuel lines before installation, and verify the quick-connect outlet and pin terminal layout match the original unit.

Quality Assurance

Delphi draws on OE supplier experience and a broad aftermarket portfolio to support consistent fit and function across a wide range of vehicles and model years. HP10128 is built as a standard replacement fuel pump hanger assembly for service work on select Explorer and Mountaineer fuel systems.
