Standard Ignition S-1490 Fuel Tank Pressure Switch Connector

Fuel Tank Pressure Switch Connector for GM Applications

Standard Ignition S-1490 is a fuel tank pressure switch connector built for direct electrical repair on select GM vehicles. It uses a 3-wire, male connector design with female pin socket terminals and a 16-inch harness for serviceable replacement of damaged or corroded wiring.

Key Features

• Fuel tank pressure switch connector for air and fuel delivery electrical repair
• Male connector gender with female pin socket terminals
• 3-terminal, 3-wire configuration
• 16-inch harness length for routing and splice repair
• Includes butt splices for harness connection
• Standard Ignition S-1490 for OE-style connector replacement

Product Details

Standard Ignition S-1490 is engineered for technicians replacing a failed fuel tank pressure switch connector on GM platforms. The connector is designed with high-grade materials to support solid conductivity and consistent terminal contact, helping restore the electrical connection at the fuel tank pressure switch. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a practical repair solution for vehicles such as the Chevrolet Colorado, GMC Canyon, and Chevrolet Equinox, as well as other listed Buick, Cadillac, Chevrolet, GMC, and Pontiac models. Standard Ignition S-1490 is also referenced by part number 19179274.

Common Repair Issues

• Broken or heat-damaged fuel tank pressure switch connector
• Corrosion at the terminal interface
• Intermittent fuel tank pressure signal loss
• Hard starting or drivability concerns tied to evaporative system electrical faults
• Wiring damage near the connector pigtail

Installation Notes and Tips

• Verify connector style, terminal count, and wire layout before installation.
• Match the harness routing to the original repair path to avoid strain on the wires.
• Use proper splice and crimp practices when joining the pigtail to the vehicle harness.
• Inspect the mating switch and surrounding wiring for heat, corrosion, or terminal spread before reconnecting.
• Confirm fitment for the specific vehicle, including 2015-2022 Chevrolet Colorado, 2015-2022 GMC Canyon, and other listed GM applications.

Quality Assurance

Standard Ignition draws on decades of electrical component development and uses materials selected for conductivity and connection integrity. The S-1490 is built as a repair-focused connector for technicians addressing original equipment connector failure on supported GM vehicles.
