Fuel Pump Wiring Harness for OE-Style Repair

The Delphi FA10021 fuel pump wiring harness is a standard replacement part for restoring electrical connection at the fuel pump. Built with Delphi’s OE heritage and aftermarket engineering knowledge, it is made for direct-fit service on select Dodge truck and Dakota applications.

Key Features

  • Fuel pump wiring harness for air and fuel delivery repair
  • 6.50-inch length for application-specific routing
  • Plug-in connector design with 4 male blade terminals
  • Plastic jacket material for standard replacement use
  • Includes fuel pump wiring harness and instruction sheet
  • Delphi part number FA10021 for catalog matching and service lookup

Detailed Description

Delphi FA10021 is a fuel pump wiring harness engineered as a standard replacement for select 1996-1997 Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, and 1996 Dodge Dakota applications. It uses a plug-in connector with blade terminals and a 4-terminal male configuration to support a direct electrical interface at the fuel pump. The 6.50-inch harness length and plastic jacket help maintain a clean, service-ready fit in the fuel delivery system. Delphi FA10021 is backed by the brand’s long OE supply history and is built for vehicles that need a replacement fuel pump harness rather than a universal repair solution.

This part cross-references CFA10021 and FPW14 for the same application.

What It Helps Fix

  • Intermittent fuel pump power loss caused by damaged wiring
  • Corroded or heat-damaged connector terminals at the tank
  • Broken harness insulation affecting fuel pump electrical continuity
  • Poor fuel pump operation related to loose or worn plug connections
  • Service issues during fuel pump replacement on Dodge Ram and Dakota models

Installation Notes and Tips

Compatible With 1996-1997 Dodge Ram 1500, 1996-1997 Dodge Ram 2500, 1996-1997 Dodge Ram 3500, and 1996 Dodge Dakota. Clean the fuel tank before installing the fuel pump to prevent future seal problems, as noted in the fitment data. Verify connector style, terminal count, and harness routing before installation. Delphi FA10021 should be matched to the vehicle’s original fuel pump wiring configuration for proper service fit.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge from work with major automakers. That background is reflected in the FA10021 fuel pump wiring harness, which is built as a standard replacement part for service-focused repairs.
