The Aeromotive AER66171 VaporWorx Pulse Width Modulation Controller Kit is designed to manage fuel pump operation in Radium Engineering 3x and 4x fuel pump surge tank systems. This controller kit is engineered for supercharged applications that require precise fuel pump control, helping deliver dependable performance and efficient operation under demanding driving conditions. Its application-specific design makes it a practical solution for performance fuel system installations using compatible Radium Engineering surge tanks.
The VaporWorx PWM controller regulates fuel pump speed through pulse width modulation rather than operating the pumps at full output continuously. This approach can help reduce unnecessary electrical load, limit excess fuel heating, and support consistent fuel delivery when properly integrated with the vehicle’s fuel system. The Aeromotive controller is intended for automotive use and is supplied as a complete kit for the specified triple- or quad-pump surge tank configuration.
This Aeromotive fuel pump controller is not CARB approved and may require acknowledgement of that status before installation or use in applicable areas. Verify vehicle compatibility, fuel system configuration, wiring requirements, and installation procedures before purchasing. The AER66171 is intended for use with compatible Radium Engineering 3x/4x fuel pump surge tank systems and should be installed by a qualified technician familiar with high-performance fuel systems and electronically controlled fuel pumps.
