Aeromotive Billet Speed Controller for Electric Fuel Pump RS003C0118 low Ohm contact brush/spring andFor any pump, on any type of vehicle, the Aeromotive Fuel Pump Speed Controller (FPSC) minimizes fuel heating and vapor lock problems by matching the duty cycle of the fuel pump to engine RPM. At low demand, the FPSC slows the fuel pump down, reducing the chance of suction side cavitation and vapor lock. When demand increases, the FPSC returns the fuel pump to 100% duty cycle for maximum flow. Its like an automatic transmission for your fuel pump.
