Solid-State Relay Fuel Pump Interface Module

601-0373

The Precision Raceworks Solid-State Relay Fuel Pump Interface Module is designed to enable reliable digital PWM control of high-current fuel pumps when used in conjunction with a solid-state relay. This module conditions and manages inductive load behavior, allowing stable, noise-free operation during high-frequency switching without compromising relay or control electronics.

Engineered for automotive and motorsport applications, the interface module seamlessly integrates with our pump activation harnesses for a true plug-and-play installation with our pump activation harnesses. No cutting, splicing, or custom wiring is required. Simply connect the module inline with the appropriate harness and solid-state relay to achieve precise pump modulation.

This solution is ideal for builds utilizing ECU-based PWM fuel pump control, offering improved drivability, reduced electrical stress, and enhanced system reliability compared to traditional relay-only setups.

Features:

• Designed specifically for use with solid-state relays

• Enables clean, stable PWM control of fuel pumps

• Fully plug-and-play with our pump activation harnesses

• Protects control electronics from inductive voltage transients

• Automotive-grade design suitable for performance and racing environments

Requirements:

• Solid-state relay (not included)

• Compatible ECU or controller capable of PWM output

Whether you’re upgrading an existing fuel system or building a high-performance setup from the ground up, the Solid-State Relay Fuel Pump Interface Module provides a clean, professional solution for modern fuel pump control.
