Delphi FA10004 Fuel Pump Wiring Harness

Delphi FA10004 Fuel Pump Wiring Harness

Delphi FA10004 is a standard replacement fuel pump wiring harness built for direct service on select GM vehicles. It uses a 4-terminal female plug-in connection with a plastic jacket and 17.7-inch length for a clean harness replacement during fuel system repair.

Compatible with applications such as the Buick Century, Chevrolet Impala, and Pontiac Grand Prix, this harness supports reliable electrical connection at the fuel pump. Delphi’s OE heritage and broad aftermarket coverage help ensure the part reflects the same engineering focus used in original equipment service.

Detailed Description

The Delphi FA10004 fuel pump wiring harness is built for vehicles that need a replacement electrical lead between the fuel pump and vehicle harness. Its pin-style, 4-terminal female connector and plug-in design support a direct service fit on listed applications, while the standard replacement construction is suited for routine repair work. This part cross-references Airtex Fuel Pumps WH3001 and Carter 888-543 for the same application. For shoppers searching by vehicle, this harness is a fit for Buick Century, Chevrolet Cavalier, Chevrolet Impala, Pontiac Grand Prix, and other listed GM models from 1997-2005.

What It Helps Fix

• Intermittent fuel pump power caused by damaged wiring
• Corrosion or heat damage at the pump connector
• Broken, brittle, or frayed harness insulation
• Poor electrical contact at the fuel tank connection
• Fuel delivery issues traced to wiring faults rather than the pump itself

Installation Notes and Tips

Clean the fuel tank before installing the fuel pump to prevent future seal problems, as noted in the fitment guidance. Verify connector style, terminal count, and harness length against the original part before installation. Confirm the vehicle application by year, make, and model, especially on Buick Regal, Chevrolet Lumina, and Oldsmobile Intrigue service jobs where exact harness routing matters.

Quality Assurance

Delphi builds this replacement harness using OE experience and supplier knowledge developed through work with major automakers. The FA10004 is part of a broad aftermarket portfolio covering multiple vehicle years and service needs, with construction intended to meet standard replacement expectations for fuel system electrical repair.
