Fuel Pump Connector for GM Applications

Standard Ignition S2904 is a fuel pump / sending unit connector built for direct service on a wide range of GM vehicles. It uses a rectangular connector shape with a male housing, female blade terminals, and weatherproof sealing to support a secure electrical connection at the fuel tank or sending unit.

Use this connector when servicing a damaged fuel pump wiring plug on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Camaro. The S2904 is also a fitment-based solution for many Cadillac, Buick, and Chevrolet models across 2004-2024 applications.

Key Features

  • Fuel pump / sending unit connector for electrical repair at the tank module
  • Standard Ignition S2904 replacement connector with rectangular housing
  • Male connector body with female blade terminals
  • Weatherproof sealed design for added connection protection
  • 3-wire configuration with 12-18 gauge wire support
  • Harness length: 13 in. / 32 cm
  • Includes splice connectors for wiring repair work

Detailed Description

The Standard Ignition S2904 is a service connector for fuel pump and sending unit circuits where the original plug has heat damage, corrosion, broken locking tabs, or terminal wear. Its 4-terminal blade layout and sealed housing help restore a stable electrical interface without changing the fuel system component itself. This part cross-references EC2804 and PT2877 for the same application.

Compatible With Chevrolet Camaro, Chevrolet Colorado, GMC Canyon, Cadillac Escalade, Chevrolet Silverado 1500, GMC Sierra 1500, and other listed GM platforms, the S2904 supports repair work across multiple model years. It is a practical choice for technicians addressing intermittent fuel delivery or sender signal issues caused by connector failure. Standard Ignition S2904 is also referenced by part number 13585475 in related applications.

Common Repair Uses

  • Broken or melted fuel pump connector housing
  • Corroded terminals causing poor electrical contact
  • Intermittent fuel pump operation from damaged wiring at the tank
  • Fuel level sender signal loss from terminal wear
  • Connector replacement after harness-side repair

Installation Notes and Tips

Match the connector shape, terminal style, and wire gauge before installation. Verify wire routing and polarity against the vehicle wiring diagram, then splice and seal each circuit carefully to maintain a reliable connection. Because this connector is listed as weatherproof sealed, it is suited for exposed underbody and fuel tank locations when installed correctly.

Quality Assurance

Standard Ignition supplies replacement electrical components for service and repair applications. The S2904 is built as a direct-fit connector solution for the listed vehicles and is backed by Standard Ignition’s product engineering standards for automotive electrical service parts.
