Important installation notes

Never route the fuel pump's main power through this switch. Use it to activate a suitable relay. The switch activates only under positive pressure, is not factory-calibrated and must be set according to the installation instructions. It can be used with compatible oil, fuel or coolant systems but must not be used with brake fluid.
