Solid State Relay Upgrade Kit

The Precision Raceworks Solid-State Relay Upgrade Kit provides everything needed to convert your fuel pump system to full PWM control, combining our Solid-State Relay Fuel Pump Interface Module with a high-quality solid-state relay for a complete plug-and-play solution. Designed specifically for use with our pump activation harnesses, this kit delivers smoother operation, improved reliability, and enhanced fuel system performance compared to traditional relay setups. One kit is required per pump being controlled. By transitioning from simple on/off relay control to true PWM modulation, your fuel pump operates only as hard as the engine demands. This results in cooler fuel temperatures, reduced pump wear, and quieter operation—while maintaining consistent, reliable fuel delivery even under extreme conditions. When paired with a Motiv Re|Flex+, this kit performs best at 200 Hz for optimal control and stability. Ideal for street, track, and high-performance builds, the Solid-State Relay U
