FUEL SYSTEM REQUIREMENTS
External Fuel Pump
Fuel Tank Air Intake
We cannot guarantee the correct function on all motorcycles with a fuel pump. The external fuel pump may cause problems with measuring on some motorcycles. If this problem occurs, you can return FuelGaugePro to us and we will return your money back to you. Device must be in intact condition.
It is not possible to install the gauge on the bikes equipped with evaporative loss control system. This system makes the vacuum in the tank that affects the hydrostatic pressure in the fuel tubes measured by the Fuel Gauge Pro Sensor.
