12V Fuel Pump Relay Sonzrod 40A SPDT Automotive Silver Alloy

Description

Product Overview

The Sonzrod 12V 40A fuel pump relay is engineered for durability and performance in demanding automotive environments. Constructed with a robust plastic housing and silver alloy contacts, the relay offers excellent conductivity and resistance to corrosion, ensuring consistent operation even in harsh climates. The SPDT (single pole double throw) configuration provides flexible circuit control, allowing the relay to switch between two distinct pathways based on voltage presence. Rated for a continuous current of 40 amps, it comfortably handles the power demands of fuel pump systems, cooling fans, and other critical accessories. The plug‑in mounting style aligns perfectly with the original equipment manufacturer (OEM) slot, eliminating the need for modifications or additional wiring. Each unit measures 1.4 x 0.9 x 0.6 inches and weighs just 2.39 ounces, making it a compact yet powerful solution for a wide range of General Motors models, including Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Buick Enclave produced between 2000 and 2024.

Usage

Designed for both professional mechanics and DIY enthusiasts, this relay fits seamlessly into the fuel pump circuit of compatible GM vehicles. When the ignition is turned on, the relay receives a 12‑volt signal that activates the internal coil, causing the contacts to close and supply power to the fuel pump. This reliable activation prevents fuel starvation during engine start‑up and maintains steady fuel flow during operation. The relay also excels in auxiliary applications such as controlling electric cooling fans, AC compressors, and other high‑current accessories that require precise on/off switching. Its heat‑resistant housing allows it to operate safely up to 85 °C, making it suitable for engine bays where temperature fluctuations are common. Installation is straightforward: simply locate the existing relay, disconnect the wiring harness, and insert the Sonzrod unit. No soldering or rewiring is required, and the included three‑relay pack ensures you have immediate replacements for future maintenance or unexpected failures.

FAQ

What vehicles are compatible with this relay?

The relay is compatible with a range of General Motors models produced from 2000 to 2024, including Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Buick Enclave. It replaces OEM part number 13502751 and fits the standard plug‑in relay slot in these vehicles.

Can this relay be used for applications other than the fuel pump?

Yes. While it is optimized for fuel pump circuits, the 40 A rating and SPDT design make it suitable for controlling high‑current accessories such as electric cooling fans, AC compressors, and other auxiliary loads that require reliable on/off switching.

What is the warranty period for the Sonzrod relay?

Each relay comes with a one‑year limited warranty covering manufacturing defects. If you encounter any issues within this period, contact our support team for a replacement or refund.

Do I need any special tools to install the relay?

No special tools are required. The relay is a direct plug‑in replacement: simply disconnect the existing relay, insert the Sonzrod unit, and reconnect the wiring harness. The process can be completed with basic hand tools such as a screwdriver if the relay housing is secured with screws.
