For vehicles using engine combinations that provide little or no manifold vacuum required for braking. When vacuum drops below 15 of vacuum the CVR Electric Vacuum Pump activates and increases the vacuum level to 20 of vacuum. Complete self-contained unit. Simply connect the positive/ negative power and the unit will regulate the vacuum level itself. Unit can be mounted in any position. Precision machined. Cast aluminum construction. Precision bearings and balanced crank reduce vibration drastically compared to most conventional diaphragm pumps. Self-contained electronics for ease of installation. 12 volt, 4 amp draw.
