Whether you're cruising or running wide open throttle, Aeromotive's billet fuel pump controller is able to sense engine RPMs and deliver the correct voltage to the fuel pump(s). An adjustable knob lets you calibrate the desired RPM level, and an LED indicator confirms ignition hookup, verifies energization of the manual override circuit, and indicates the circuit is providing full voltage to the pump(s). The housing is constructed from 6061-T651 billet aluminum and anodized in a beautiful bright dip red finish for good looks. Its low operating temperature allows mounting in any location, and it comes complete with everything needed for installation.
