*Billet Fuel Pump Speed Controller, P/N 16306* (This Part # replaces Part # 16302) For any pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes hot fuel handling problems for in-line pumps in bypass systems and it will also keep T-style pumps cool in static systems, extending fuel pump life. Sensing engine RPM, the FPSC kicks your fuel flow into high gear when you need it, but reduces pump speed and flow to keep things cool when you don’t. It’s like an automatic transmission for your electric fuel pump. When you’re cruising, Aeromotive’s Billet Fuel Pump Controller automatically steps voltage down to the Fuel Pump at lower RPM, then it continuously monitors engine speed, stepping voltage and flow back up when needed. The RPM step-point is adjustable, allowing calibration for your specific application
NOTE: For use with returnless fuel systems only.
