Aeromotive Pump Speed Controller 2014-subaru-impreza-wrx-sti-esi7728397 We offer the optional ADDFor 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. It? s like an automatic transmission for your fuel pump.
